According to Frankl, what were the communal showers like? What was the attitude of the prisoners as they entered their first communal shower? Why is this important to Frankl?

Frankl writes that they were "made to run from the station, past electrically charged barbed wire, through the camp, to the cleansing station" they were forced to give up all of their personal belongings including rings and watches, and they were shaved (Frankl describes this -- "not only our heads were shorn, but not a hair was left on our entire bodies") before entering the showers. Despite their situation, Frankl writes that prisoners saw humor in the showers, and were thankful that they were under real water, not in the gas chambers. Frankl writes that humor, from this early moment on, became an important part of survival for the prisoners.
