symbiosis

I like word symbiosis; I like when a single word encompasses a large concept. Symbiosis: two beings in a mutually beneficial coexistence.

We need nice clean words for other things, such as:

That sneaky manoeuvre we use to surreptitiously check for body odor;

The fact that it's lonlier sitting next to certain people than sitting alone;

The sleep-convulsions you have when you dream of falling;

The feeling you get when your wonderful new lover writes you a poem, and it's sappy and awful but also the first and only poem anyone has ever written you.
