oh, i'm pretty old. 21 at the moment, but turning 22 in a couple of weeks. and i live kinda alone? i have a flatmate. but i don't really live at my parents' house anymore, if that was what you were asking about. that's not creepy, don't worry. at least i don't think so.
This sounds exactly like the time my 7 year old cousin's friend came over to play. I was supposed to watch them, and I was doing a pretty good job, but then they found my pads DX they thought they were parachutes and they attached them to their figurines. It was super embarassing.
