I do it all the time because I'm scared of misgendering ppl and only 1 of my friends is cis

my brain wants to use gendered pronouns but i think it just naturaly come to me as saying "they" now, just out of being respectful and not being bothered to ask

Yep, I do it, and it helps in making sure to stay affirming, but it also gives me a chance to use non gendered pronouns as kinda a radar. If they don't like it, I shouldn't be interacting with them.

YES

If only one of your friends are cis then you don't have a normal friend group

idk what that's supposed to mean is that a good thing or a bad thing

I would argue it's not a very good thing

Oh

no
Infact I'm not used to calling people 'they' at all I have to remind myself
