I think this has happened a few two many times recently for it just to be a phenomenon in the people around me - walking back into a room to see someone - always a girl - flicking through my phone, and as a rule not particularly bothered about being busted either.

My flatmate's friend, who I've met exactly once, did this last night when I went to the bathroom, then proceeded to ask me who such and such was. I wouldn't dream of doing that to one of my friends, and I'd certainly feel pretty mortified if I was caught.

Given there's obviously some personal stuff on there so do I need to start taking it with me.....or find better friends?
