Archetypes and Everywhere people

My friend Shannon (aka Sheldon) I think was the first to tell me about the concept of Everywhere People. I'd never really been aware of them until I got to Madison. Everywhere people are, as the name suggests, the people that you see everywhere you go.
However, another one of the requirements is that you have to not know them. They aren't friends, or coworkers, or the person that gets on at the busstop with you. Instead, you see them on the streets wherever you're walking, they're at the store buying things when you are, etc. The people you see wherever you go.

I really haven't experienced this much since leaving Madison. It may be a phenomenon that only occurs under certain circumstances. However, I have discovered a new pheonomenon which I can't really label except for "archetypes". If someone has a better idea, let me know. But these are the people that you actually meet who remind you incredibly of someone else you know. I never noticed it much until I got to law school. But these people often tend to look similar to (sometimes frighteningly so) someone else you know and also often may behave in similar ways. It's just eerie (eery?).

I'd never really noticed this before, but I have often heard, "You remind me of so and so" or "you look just like blah blah blah." I don't know if I do. But it always creeps me out. I'd like to have a convention of these people who look and/or act just like me in order to determine how similar we really are. Although I'd probably just end up feeling disappointed. Or really creeped out.
