I do this, I love to watch people (non creepy way) when I am in a cafe, or waiting for a bus or something.
Because i'm into film and scriptwriting it also helps me a lot watching how real people interact, talk, body language etc.
It's interesting to me how there are over six billion people on this planet all with their own family, job, routine, hopes, worries and a million other things yet no on speaks we just share this planet and keep to ourselves.
ot: I also like to observe what people wear, I like seeing peoples styles compare them to others, how it all looks, if it'll suit me etc. Am I odd?
Nah, everybody does 'people watching'. Some do it unconsciously, some do it on purpose. I do both. It's fun.
