When I was in school in the Dark Ages, after gym we were supposed to shower. The water was always COLD! the Anglo kids would wrap a towel around themselves, dash under the shower head and get a little water on their head, the run out rubbing like they were all wet.
The Hispanic boys, jumped right into the cold water and lathered up with soap and got clean! They probably did not have hot water at home and were used to cold water.
OK, I tried to dodge the showers also.
We didn’t have a shower at home, only a bathtub with water from our cistern which my mom heated on the stove. Everyone used the same water. I was the youngest so always bathed last. Kids today would never survive but it was normal for us.
