Do you feel like you’re on the inside or the outside?
Depends very much on context.
At many levels, I am happy being on the inside, determining who comes in, and when I venture out.
At other levels I am outside, trying to find the key to get in.
All life seems to require semi-permeable boundaries at different levels, letting some things in and out, while keeping other things in or out.
At every different level, what distinguishes us from the environment around us is the way we uptake some things and keep others out.
So yeah – doors are important – any which way.
