My brother and I took an overnight bus from Guadalajara to Mexico City about 1988. First-class busses are nice, but the ride is long and tiring.
About dawn there was still some time left before getting into Mexico City, so I thought, and I had to go to the bathroom. A real session. Sitting.
I always travel with my own roll of TP, so I was set.
I got in there, and the translucent glass with a view to the outside had been replaced with clear. Weird, but no problem as we were still out in the country.
As I got going, suddenly we were in multi-lane slow-moving Mexico City traffic with many vehicles as high as the bathroom window, and then some.
Oh well, I’d never see any of them again. I imagined the other drivers thinking, “look at that white gringo ass pressed against that window.”
