(English is not my first lenguage!) today my mom asked me to get tortillas, she gave me the money. And i went, she already did this more than 5 times, the man (in a car) is the same as always, i already meeted him, i gave him the money and he handed me the pack of tortillas but he asked where i did study, it might be an innocent question. But i really don't want to give my personal information to strangers, i felt really uncomfortable and got pretty weirded out. I said "oh just, an highschool"
He cames to different streets and the one where i live, since many people buy, so he would know well the paths around. There isn't many schools around, so the probability of him knowing where could be a little high.
My point is, im pretty shy, if this ever happens again, what could i do to give a more natural response but still not giving information? Like i said, im too shy to say "i'm sorry i don't feel comfortable answering a question like this" so, instead of just saying "oh just, a school" i would prefer saying something else.
