I haven't had a girlfriend in a very long time and I'm kinda out of the loop. I don't consider myself attractive, although I used to get told I am a lot when I was younger (I'm 29 now) and to be honest, I'm really shy around women. But lately I've noticed quite a few different women smiling at me for no reason. Just out and about. I'd like some female opinions, what reasons could be behind women smiling at men who they don't know? Is it just being polite? Or are they attracted to me? Would a woman smile at an ugly stranger? Here's the scenario for todays situation. I was locking my bike up outside a supermarket and this old guy was sitting right infront of me with this really cool dog, pitbull I think. Then (what I assumed was his daughter) came along and her bike was parked/locked up next to mine, she said a few words to the old guy and proceeded to unlock her bike. I was going about my business locking my bike up. I was bent down putting the lock on and you know when you can just feel eyes on you? I looked up and this really attractive woman who was about 2 feet away from me looked right into my eyes and smiled really sensually. I could've read it wrong regarding the sensual part, but she definitely smiled right at me. And it was a broad, warm smile. I tried smiling back, but I'm useless at that kinda thing and it probably came out wrong and I just locked my bike up and went into the supermarket. There was a time a few weeks ago I was in a Vietnamese restaurant with two of my friends and a woman was sitting alone and she was constantly looking over at me and smiling too. In none of these cases have we ever exchanged a word, just smiles. This probably all sounds retarded, but I'm so not used to women finding me attractive these days. When I was a kid/teenager, girls used to throw themselves at me. But I don't go out much anymore and I've also had a lot of negative comments about my appearance too and I'm severely insecure. So women, do you smile at strange guys and if so, is it just out of politeness? What other reason could there be for doing it?
