Random I know, but I did this today, and holy crap that was embarrassing. I was in the library and I don't know what happened, but I was zoning out and then when I got back my awareness, I was starring at some girl and she was giving me a strange look like I was some kind of a creep or something. SO EMBARRASSED!
haha yeh, I've been there before. good thing its a complete stranger though eh? I did it accidently to this girl in high school my soph year I think. that turned out pretty awkward all the rest of school
