One boy is a teen. If anyone needs a shower it is a boy/man.
The kids will end up being social rejects. I wonder if the parents realize it? Probably not.
What part of the country? High humidity, high temperatures?
BTW, water in the bowl will eventually evaporate and all is left is distilled urine. Wonderful.
I agree that teens need to shower. My son is 15 and takes two showers a day. One in the morning and one after school (he takes weight lifting). I never had to say anything either. Maryland can have some high humidity.
