A friend who teaches first grade is talking with the children in class:
“I’ll explain how a family tree is formed. First, people get married, then they have children, and those children also have children. In this way, new branches appear, and the tree grows.”
A hand shoots up, and one of the children exclaims, “Teacher! Teacher! Not everyone has children.”
Before my friend has time to respond, a girl in the front row yells, “I know! A woman who doesn’t have children is called a virgin!”
