Input: Text: i was talking to this guy and telling him all about my idea of what happened to toronto in the fallout universe. when i finish he say, "i can tell you must be a gta native". i tell him i've played a couple of them but was more into fallout. he laughs and says, "so you aren't from the greater toronto area?" i tried to laugh it off but i know i made myself look like a complete idiot.

edit: i didn't expect anyone to see this. i was posting it because it happened i had nothing else better to do.

TIFU by not knowing what GTA meant.
