Why don't peacocks perform jokes?

When the silly daughter came home, she said happily to her mother, "He praised me for being beautiful, like a peacock."

Mom was not happy at all: "silly boy, he didn't praise you but hurt you."

The daughter didn't understand and asked, "Why do you say that?"

Mother said, "He said you were like a peacock. You're a daughter, a peacock at best. A female peacock won't open her screen. How can it be beautiful? ! "
