It's a cliche, so I knew it was inevitable that we'd hear the question sooner or later, but the whys have hit our household full force.
"We need to stop at the gas station to get gas."
"Why?"
"Because the gas light went on. The car needs gas."
"Why?"
"The car is hungry for gas. It's saying 'feed me.'"
"Why?"
"Because cars need gas to run."
"Why?"
"Because that's how they work. Without gas, they won't go."
"Why?"
"Because I said so."
"Oh. Because."
