I simply adore people watching. Strangers that is, not a stalker! I could do it all day and I have.
When I graduated Art School me and my friend did almost all of the Art Shows at the shore. It was fun, we made a couple of bucks, met other artists, swapped art, got a tan, and had an excuse to rent a motel room.
You're typical win win.
Normally I would find myself sitting on the railing if there was one, working on my tan and watching the people.It made the day fly, sales made the day fly too, but people watching was easier. Well, I learned how to act at an art/craft show at least, the do's and don'ts as it were. But lets get back to people watching.
Another great place to people watch is at Trade Shows and Weddings, I have taken up smoking at weddings so I can go out and mingle and feel at one with the other smokers. Turns out it's a special private club, and a great reason to excuse yourself when you find you are bored to tears. Wish I had started it years ago.
You need to be discreet, if they know you are watching they show off, sometimes I start up a ridiculously personal conversation, especially with young people. I feel I am at the age that I can finally get away with it without fear that someone thinks I'm trying to pick them up.
So next time you go out I'll be the one not paying attention, but watching every movement.
Don't be fooled there are many of us.
