All the examples you have given are quite normal and actually if I may say quite sweet personality quirks.
I totally get what you mean, when you feel you are massively different from most people (I am too) you think you have to almost blank yourself to present as beige but that’s not true, you can show these things but don’t let them dominate and pick when. It sounds like you haven’t found your tribe and so you are around people who are quite different to you a lot of the time.
i actually I think part of the problem is that you have had it reinforced by different people that the way you behave is inappropriate when actually (although I know it will be hard for you to work this out) that it’s just about sometimes choosing when to not do this stuff but it sounds like you actually do understand there is a time and place when you describe the raisin thing and not commenting when others are eating them.
sometimes it might be about tone I think, so I’ll say something weird but in an amusing tone rather than with a serious tone and it lands better. Or who you share these thing with as some people just can’t understand that there is a spectrum of personalities out there and automatically think if they aren’t like me they are odd but that’s more about them than you OP!
i have done similar to all your examples. Occasionally I get the reaction you get but mostly not but I do kind of pick when.
I have more than once said in response to do you want tomatoes oh no thankyou they are the devil’s fruit. I say it jovially and the other person has laughed it I probably wouldn’t say it to a serious type of personality person.
i used to call my cat and now call my fish my little chickens in a im talking to a small child tone but I wouldn’t do that in front of people I didn’t know because it might be seen as weird.
I would have no problem using the lovely sounding fan you described but I probably wouldn’t use it in a meeting for example or at a more formal dinner etc but ye fuck someone else if they judge your poor hotflushing self if they judge you for it!
iv also said hello to animals but again I might not if I was with a more serious type person than me.
oh and by the way there’s absolutely nothing wrong with your interests I like both of those two but I get not everyone does so I wouldn’t bang on about them to people who I knew probably weren’t but I would hope they wouldn’t bang on to me about say love island or strictly if that makes sense.
i think this is a long post that boils down to we all need to kind of fit in a “normal” (hate that word) so show glimpses of your true self because nothing you have said here is weird or wrong! But know how to show a bit without opening the whole dam.
i say that not because you are weird but that is what WE ALL DO in public. We share a bit of our uniqueness but hold back a lot of it and save it for our people when we feel safe and comfortable (husbands or friend etc) and kind of tone ourselves down to a degree to not stand out too much in front of strangers.
you sound lovely @Sunkisst dont let other people form your opinion of yourself, be who you are because there is nothing wrong with that!
