The Summer Inquisition

Luke has been rampant with questions the last couple of weeks.
"Why do we wear shirts?"
"Do monkeys have tails?"
"How does the beach work?"
"Do all Daddies work at CVS?"
"Where's your penis?"
"What makes the sun move around in the sky"

Not all of these questions are easily answered, and you can bet that each answer will be followed up with, "Why?" For instance, I told him I loved him this morning. "What does, 'I love you' REALLY mean?" he asked.
"Well, it means that I care about you a whole lot."
"Why?"
"Because you're my son and I like spending time with you."
"Why?"
"Because you're funny. You make me laugh a lot."
"Why?"
"Just forget I said it."
