Pretty normal
A woman went to see her psychiatrist. "I'm really concerned," she said. "The other day I found my daughter and the little boy next door together, naked, examining each other's bodies and giggling."
The psychiatrist smiled. "That's nothing to worry about, it's pretty normal."
"Well, I don't know," said the woman, "It worries me. It worries my daughter's husband too."
