Sometimes I like to wave at people. On tour buses they will almost never wave back, off tour buses they will sometimes. In the latter case I'm not really making a judgement, but in the former case it feels like a safari kind of thing.

Of course it's a subjective feeling I have, but I think this is different than people watching which I suspect you're referring to.

In the your comment I've started asking people about their cool/interesting clothes. Some people are receptive others aren't. This is an aside from what I was saying but just want to mention I've started having fun and interesting conversations that way.
