It takes an effort to attempt to mold students and some people into civilized members of the community. It only sometimes works. Among adults, I liked to use a joke as an example of that effort. A little girl was out with her grandmother when they saw two dogs mating. “What are they doing, Grandma?” asked the girl. The grandmother was embarrassed and said, “The dog on top hurt his paw, and the one underneath is carrying him to a doctor.”

“They’re just like people, aren’t they, Grandma?” said the little one. 

“How do you mean?” asked Grandma.

“Offer someone a helping hand,” said the little girl, “and they fuck you every time.”
