That dreadful point in the day where the sun is too low in the sky to be blocked by your sun visor, but too high for it to be dark.
I was trying to nap on the car ride home, but we were so deep in malsolchroning that the sun shined through my closed eyes no matter how I was sitting. I had to take my jacket off and put it over my head, like that's a remotely normal thing to do.
