I hear ya Lil Me.
I also don't like it when friends/families start snooping around our stuff and then not put it back where it belongs.
Maybe it's just me, but when I go to a friend's place, I wouldn't start touching their things and snooping around unless I have permission from them by asking if it's ok to check out their collection of books (for example). BUT, we have some friends, who would just snoop at our stuff, and doesn't put the items back. First of all, they never asked, and secondly, they didn't put it back to the correct place. GRRRR, pisses me off.
