Who n why? If you cant answer here dm me. Anyway you shdnt be scared to talk to anybody here or elsewhere. Just try to be friendly n talk according to the situation you find yourself in. Relax n accustom yourself to the atmosphere. Or sometimes if you need to leave a tense or hostile situation, you can leave.
Talking or interacting is a 2 way street. But im an introvert, sometimes if im with friends irl, i used to just sit n be silent with them while doing our own thing. Not always but when youre with chill friends, silence is nice too. Or maybe im rmbring wrongly.
