Robert Mitchum in the movie Night of the Hunter, playing a religious fanatic, had "love" and "hate" tattooed on his fingers, love on one hand and hate on the other.
I have, temporarily, hands demonstrating "wasp-stung" and "not-wasp-stung" without any tattoo. This is the second time this summer that I have been stung by the more aggressive sort of paper wasp. The swelling goes away, well it did last time anyway, in a day or three.
Back in the early 70s, maybe 71, I lived in Fortuna in Humboldt county in northern California. I moved there from San Francisco and had good friends to visit in the city. I would leave my house at 8 AM and hitchhike to SF, usually arriving in 6 or 7 hours. Almost as fast as if I had driven myself. After a few days I'd hitch back north. One of those trips found me somewhere a bit north of Ukiah at the end of one ride with my thumb out for another. In the way of things back then it wasn't long till a van pulled over, stopped about fifty feet away, and the rear door swung open. I trotted over and jumped from the bright sunlight into the dark back of a windowless van. No fewer than three voices welcomed me with "Hi Roger." Neighbors and friends from Humboldt. I was dropped off in Fortuna and enjoyed a leisurely 10 minute stroll home.
