Hunter was 4 years old and staying with his grandfather for a few days.
He had been playing outside, when he came in and asked, "Grandpa, what's it called when two people sleep on top
of one another?"
Grandpa was surprised but said, "It's called sexual intercourse."
Hunter went back outside, but returned soon and yelled, "Grandpa, it isn't sexual intercourse. It's called bunk beds and Jimmy's Mom wants to talk to you."
