This if nothing else

Sometimes I'll be walking down the street and I'll see a pretty girl walking by. Sometimes they smile at me and I'll smile back. Over time I have had the the chance to talk to some of these girls, sometimes become friends with them and then sometimes even more.
Before I would most automatically strike up a conversation if I could find anything to say but now by default I keep walking. It's an unfortunate thing to think about but experience has taught me that the most they could ever do for me is smile... and still I'm glad I get at lest that.
