friendship ecosystem

There's a concept I believe when it comes to the friendship circles that we keep. Those friends that invoke certain states-of-minds that we go into when we're in there company, those friends fit in an ecosytem for our survival. So if there's someone that you turn to when you get upset about work or a significant other and that person isn't there where do you turn? Someone's status is elevated in the ecosytem. It works the reverse way too. People can take up precious space in the ecosystem at the cost of another.

I can't really figure out where some people belong in mine if they belong there at all but its never good to burn bridges. I'm trying to make an extra effort to fix the bridges, even the ones I didn't touch.
