The Price of Eavesdropping

The price of eavesdropping is sometimes you hear this:

Father, singing: "I'm goin' on a booger hunt. I'm gonna get a booger!"
Daughter: "Nooooo. Don't blow my nose!"
Father: "I'll show it to you when I get it..."
[Silence, apparent aquiescence.]
Father, proudly: "Check out this huge green booger, Lu!"
Daughter, proudly: "Eeewww!"
