Symbiosis is when two different organisms live together in the same environment and each needs the other. Some relationships facilitate one another, other relationships obligate.
Ours does both.
At 38 I’ve noticed that it’s time to wax the lip. My darling husband, on the flip side, can’t see a thing. He squints at me and says, “What hair?” I give him an weird are you blind look, he says, “buy me some reading glasses”. I say I will, but never do.
Symbiosis, he’s blind, I’m hairy, we’re in love.
