People Watching

I'm using my beach vacay for some serious people watching. Between the beach, the pool, and the patio right below our room, I've already gathered some fodder for future characters or situations. I especially pay attention to the details. How people walk, gesture, carry themselves. I like to observe relationship dynamics, especially between family members. Public arenas like this are a writer's petri dish.

So that's my thought for this Tuesday. What do you pay attention to when people watching?
