Maybe it will rain.

My child wore high water pants to school today.

A friend gave him some hand-me-over pants that no longer fit her son. He grabbed them out of the closet this morning and put them on. I told him they were too short.

"How can you tell?"

"I can see."

"But I like them! They're comfortable!"

"Fine."

So yes, yes indeed, he is waiting for a flood.
