More than once, I see a cute girl pass by as I walk around, and they smile as we pass by. Okay, there are women probably triple my age who do that (prob just to be friendly) but I am probably sure some of the girls do this to show genuine interest.... (right?)
I think it's rather disappointing especially if it happens on the street, because we're probably headed somewhere. If it happens on the street again, what's the best approach to things if I catch on quickly enough and am interested? Is it usual for people to be so friendly to strangers they see only for a few seconds?
