I totally get what pps are saying about age/experience making it easier.
However even as a teen I didn't bother about what people I didn't respect or care for thought. I wasn't the geekiest, least fashionable at school but neither was I in the "in" crowd and it didn't bother me. I had the friends I respected & cared for (and the core group - we all sat on the same table in reg class - are still all in touch and we've supported each other through various life experiences) we had great fun together in our own way and we're still friends and still have the same outlook on life as each other roughly, over 30 years later.
Maybe because my home life was so shit I had a better perspective? On what was important? Eg I didn't care if people thought I wasn't wearing "cool" clothes, I wore what I liked. I also had no interest in drink/drugs, smoking etc for my own reasons so if people tried to get me to do these things I felt comfortable saying no. But equally I didn't lecture others about their choices, although if pressed I'd give my opinion.
Then in my 30's I had a breakdown (combination of trying to do too much, dealing with a nasty divorce/ex, not having any real support, then a bad car accident leaving me disabled, carless & skint!).
When things have been that bad I've found it harder to give a fuck if someone likes my hair or things I'm fat!
And yes, turning 40. Certain family relationships I realised weren't healthy so I binned them. Dd had just prior been DX with her disability too so my priority was very much our little family.
"wouldn't worry so muchabout what others think of you if you realized how seldom theydo.” Apparently Eleanor Roosevelt.
So true. As pp said - what do YOU think of others? Do you judge them on their appearance? Jobs? Lifestyle?
Most of us generally don't care we're more wrapped up in our own lives.
Even when we do notice certain things another thing MOST of us learn as we age is not to judge OTHERS harshly/unkindly and not to make assumptions.
Personally I have a people pleaser in my life who drives me NUTS because by trying to please EVERYONE they end up telling people contradictory things just because they think it's what that person wants to hear.
It's resulted in huge misunderstandings and even outright offence "but you told me you could do X activity/event with me AFTER you'd told A you were doing Y (50 miles in other direction 20 mins earlier type thing!) with them that day" infuriating! And doesn't actually PLEASE people. You just knacker yourself & end up over committed.
FAR better to be polite BUT honest.
"while I would never call myself an extrovert" extroverts aren't necessarily confident. Lots of performers are extrovert but extremely anxious to please.
A phrase I've seen on FB recently sums it up well
"You can't be everyone's cuppa or you'd be a mug!"
I do actually remember a time once a girl at school in the "in crowd" made a point of coming up to me in the playground and saying "I don't like you" and laughing. Weird. But her face when I said "I don't care. Why would I?" and walked away was apparently priceless.
As a pretty, popular girl she was USED to people wanting her to like them. She couldn't compute someone not caring less what she thought! I heard later it bothered her for weeks, I didn't think about it until someone mentioned it to me past that break time and even then I was like "oh how weird" and basically shrugged it off.
I'm not completely immune to hurtful comments I am still human, but I try to deal with them appropriately and not let them overly bother me, sometimes easier said than done.
