I was at a book store not long ago, sitting at the coffee corner, reading some books, and I noticed this one girl sitting a few tables from me... Well, I kinda check her out for a little bit going back to mind my business. I then got up, went to the restroom, and on the way back I checked her out again... Well, it turned out she was looking at me as well. I got a bit embarrassed and look away.
I wanted to approach her and have a chat with her, but she seem to be busy studying, so I give up the idea. Anyway, how do you ladies feel about being approached in situations like that? Or rather, even if I didn't catch her looking at me, would it be rude for me to approach her anyway?
