I take my showers at night, since going to bed with a day's worth of filth seems a bit disgusting to me, rather like the concept of a bath relative to a shower. Given the wait I sometimes have to endure for the common shower in the sleepers in the evenings, I am sure I am not the only one with this habbit.
As to Bill Haithcoat's observations, my own 63 years on this planet shows that showers and bathtubs are relatively new in their abundance. I can't recall having our own shower or bathtub at home until I was 12 years old; the mechanism among the non-wealthy was to share a bathroom with three other households in an apatment bulding, and party line phones were common until the mid-1950s.
Americans used to do lots more sharing and cooperating than we do these days.
