What do you do to avoid questions? I usually just say the first thing that pops into my head like when I’m asked what school I go to I say something like sushi or banana ?

random dude: hey, i heard that your brother got detention. what he do?
me: * unlocks phone and begins texing*
random dude: did you hear me? Were you even listening?
* Looks up from phone and looks around, and pretends that i see or hear nobody*
random dude: Hey! are you listening to me?!
me: *Walkes away like a boss* ??

Just like this. if its a insult i roast them. if not, I kindly change the subject or leave
Person: hey i saw your brother eat something weird (dont ask)
Me: oh.. thats really cool! hey how are you?
Person: oh im fine. hey can you talk to your brother--
me: gotta go bye!
ROASTING SITUATION INBOUND:
person: hey i heard you have a girlfriend. are you a lesbian or something? See More
me: im only a lesbian cause of people like you asking these weird questions! and no, im not.
person: that doesnt make sense--
me: gotta go bye!

ignor them
