To think the hilarity just wasn’t necessary?

I’ve just had a little internal chuckle at that mental picture… a mum and her young daughter, sitting side by side on a park bench in complete silence, gazing into the distance and ignoring the world around them while they think about dungeons.

Seriously? You sound toxic. Let me guess, everyone’s always mean to you too?

@DonnySue carry on being you. I’m a bit of a reflector and value taking time to do so. Unfortunately as a lot of responses show on this thread there is low/poor tolerance of it or of difference. I regularly need breaks in social situations. My family would never take the mick out of me for having an interest. Unfortunately you’ve just got lots of people on this thread who don’t understand having an interest and can’t stretch their brains far enough to understand it because they are too restricted by societal norms eg groups should stay together not one leave for a while and come back, or laugh at the weirdo. People who lack confidence can’t cope with an independent thinker. Boring pack behaviour and sounds like your sister, like many posters on this thread, are comfortable with a bit of low key bullying to have a laugh.

Carry on doing you and the next time they laugh at you like that just leave. Set the boundary for yourself and others that you won’t be treated like that. They’ll call you weird and tell you you’re overreacting but you won’t be in the same room as them so win win.

It's been explained multiple times by multiple posters why it's not the done thing to just leave the room if you don't like the topic of conversation. At least say you needed some fresh air or something, but ideally don't do it.

I completely relate to the wish to carry on and further explore a topic of conversation in my head - I'd forgotten until this thread that my lovely dad described me as a deep thinker in his speech at my wedding, he was the same.

The point is that it's not polite to do that in company. This isn't a point of intellect, it's a point of social skills.

The most interesting, intelligent people I've known can converse in an appropriate way about just about anything, high brow or low. They don't leave the room because the conversation has turned to someone else's interests.

I did understand it, I'm not an idiot. I think it's a pretentious thing to say to anyone!

It's not been explained why this is rude. As long as she excused herself, there could be nothing wrong in her etiquette. She didn't say she stomped off in a huff FFS. It was a family gathering, not a formal debate, so it's perfectly fine to bow out when you lose interest in the discussion.
Lots of people can't stand talking about Trump because it is often so divisive, and quite frankly, it's depressing to many people. Totally understandable.
If a subject is unpleasant or boring to you, there is nothing wrong in deciding not to contribute to the conversation.

We all know that if she decided to go check her phone, use the toilet, or any number of other reasons, people would not be calling it rude. You just admitted that wanting fresh air would magically render the exact same action proper. Etiquette is being used as a smokescreen to hide distaste for allegedly "weird" people behind.

Then think deeply when they’re not there? Or is your thoughtfulness on some sort of time limit? Can it only happen at specific times? Does it need to take place during social gatherings?

People not removing themselves from social situations to reflect does not mean they don’t reflect. It doesn’t make them shallow. To claim that it does smacks of the same level of adolescent navel gazing earnestness as the OP. It’s not thoughtful, it’s silly. I’d laugh at you, as well.

The moment when it was fresh in her mind would be lost. This happens to me as well. Later on, my enthusiasm about what was discussed can tend to wane. I may forget the details of what was said.

I was saying people are shallow if they ridicule others for being thoughtful and reflective.
So laugh at yourself for your lack of comprehension.

It's a time and place thing - it was neither the time nor the place.

It's been explained multiple times.

The sister kept trying to change the conversation, then when she succeeded OP left the room to continue thinking about the previous topic rather than contributing to the group. And then came back in and tried to change the topic back to what she wanted to talk about even though the group as a whole had clearly exhausted their interest in it.

Group gatherings involve conversational give and take, it's rude not to join in or to try to monopolise the conversation - or repeatedly steer it to something you find much more interesting than everyone else.

People have not explained why it is laughable to go off and reflect on the subject.
This is the question the OP asked about, not whether she was rude to try to change the subject.

Is it rude to get up to use the toilet? To check on dinner in the oven? To attend to a child? To check your phone messages? No?
Then we have established it is only "rude" if the object is to avoid an unpleasant subject and go have a think. Therefore, it's not rude.

Were you also a bully at school?

You sound like you're projecting, especially given you personally attacked a person just for having an opinion you disagree with. Let me guess; you're always right?

Nah I’m not - I’m frequently wrong!

is there a reason you’ve replied to practically everyone in this thread? Perhaps you’re the one who is projecting, not me.

It is when she tried bringing the conversation back on what she wanted !! She was rude. As has been established.

Because it was inappropriate to the social gathering. But you have no interest in actually trying to understand, you just want an argument so I'm out.

Meaning you can't explain why it's inappropriate.
But wait, you are bowing out of a conversation? How rude!

I've explained whyyyyyy, several times, as have several others.

Count the number of posts here. Then count my responses. Your math is way off.
You obviously don't know what projection is. Look it up.

There's a lot of autistic traits going on here; a deep, intense interest in a niche subject, that long exceeds other people's ability to maintain conversation on the theme, a need for quiet space to process and ruminate about the experience, an inability to read other peoples' experience of the situation and taking it all more seriously than others.

DS has a deep and lasting interest in weaponry and ammunition of WW2 that has lasted years and there has to be a balance of some space to express himself, but also it's not fair on others for him to regularly steer the conversation to it or to talk about it for his full attention span (which can be a verrry long time).

We all have quirks and eccentricities in our family. Some at a ND diagnosable level, some not. We laugh at each other and ourselves. Humour lightens life up. It makes it easier to manage.

I like a "buffer" at transition points. It drives the DCs round the bend that when I've finished driving, if there's no urgency, I like to sit in the car, finish a song, check my phone. This is a habit that pre-dates smart phones and I did 20+ years ago from the start of driving so it's a me thing, not a phone thing. It's not a dissimilar need for DS to have to return to the hotel room on holiday for a couple of hours between activities. But I'm aware of it and can be irreverent about it. Sometimes finding the humour stops us exploding with frustration at ourselves or others- it's not automatically mean or bullying.

At the least it's worth recognising when your behaviour differs from the norm and why that is. It doesn't mean its wrong and if it's something that can be interpreted as rudeness, if you can explain your needs, that helps people understand your intentions. (e.g. there's a difference in understanding that DS is leaving the table because he's reached his social limit and him leaving the table because he's impatient to continue a game)

Then the issue is your (and her) inability to hold a thought in your head for any period of time. That doesn’t make people who can ‘shallow’.

You said Nope. The problem is that many people are shallow and don't reflect on issues enough, so they assume other, more thoughtful people are strange to do so in response to my comment about the OP’s behaviour. Specifically, leaving a social situation to ‘reflect’ being odd and not indicative of ‘cleverness’. You did not say people are shallow if they ridicule others for being thoughtful and reflective.

My comprehension isn’t the issue, here. I continue to find you laughable. Your responses on this thread are rather manic. Perhaps take a breath. Or a moment to reflect.

Was at my grandmas earlier with DD (9). My sister, her husband and their kids were there too. We were talking about history and I was absolutely fascinated by it (I love history, especially British history) and at one point I took myself outside into the garden to have a few minutes of thinking and reflection on what we’d been talking about.
DD came out to ask what I was doing and I said “just having a few minutes to reflect on what we’ve been chatting about”.

She went back inside and then I heard howls of laughter coming from the living room. DD had told them what I’d said and they were all in stitches over it. It really ruined my thoughts and I tried to get the topic back up and running but sister kept saying everyone was still reflecting - cue more hilarity.

was what I said really that bloody funny?? Pissed off but also a bit embarrassed 😞
