Very open-ended and broad question but that's the beauty in such ideas is it not? To allow oneself the space and capacity to ponder.
I'm sitting here at the beach as it nears sunset and I begin to wonder, what do others think of as they people watch? Are they actively participating in the lives of others as they watch from a distance? Is nothing in your thoughts associated to the people around you?
As I sit here, I find myself latching onto certain people. Not certain kinds of people, but there seems to be a particular connection I find in myself with a person or group of people that I visually latch onto. That connection usually is a parallel I see within my own life, between myself and other people, with myself and my aspirations, and what I perceive in others around me.
I sit here now, watching these two young guys, maybe in their young twenties, doing jumps off a natural ledge formed by the tides and sand. They may just be friends, but I relate to them in the way I see the relationship between my brother and I. There are many thoughts roaming around at once as I watch these two. Some longing, some pleasant, some purely observational. The theme that tends to run in these thoughts of mine though, as I people watch, is that I tend to see myself in a broader picture and remove myself from my itty-bitty life, and incorporate myself into this larger relationship that I see of humanity. This is a nice place to be, and a place in my mind that tends to help me make sense of the world again.
