Dear WW: It took me a while to think of "dereistic" with a smile. How about the carpenter
in Chaucer's Miller's Tale, who builds an Ark in his basement, and when he hears Nicholas
who got goosed with a hot iron yell "Water!" thought the Second Flood had arrived
and launched his creation crashing to the floor. That's dereistic thinking at work.
Incidentally, I have trouble with that part of the story. I dpibt tjat the smith would work after
dark, or the carpenter either for that matter.

teenaged boys, descamisado at the beach………. beachboys ……. after a long day descamisado in the sun
Mmmm….Evidently a consistent image WW, could it result from some dereistic mental activity?

I may write a little ditty this weekend entitled "Descamisado in the Sun"
Dare I hope you will share it?
