I can totally relate to this, especially the 'first impression' thingy hahaha it makes us think it's impossible to be friends with these people but then you'll end up waking one day and realize you've become inseparable to one another.
I've been teased a lot in my elementary days too, but the moment I stepped in HS I learned how to throw punches hahaha, but yeah, we all grew up and became close friends at the end.
