"however"

My preschool son and I were having lunch. I was preparing his sandwich while he was beginning to munch on apple slices or chips.

"Mama? Would you read this book to me while we eat?"

"Sure," I responded. "I have to use the bathroom first, however."

"Eeeew!" he exclaimed. "You're just going to let it run down your leg or onto the floor or somethin'?"

It took me a moment to understand his reaction. Then I realized that it was all about comma placement and pauses. He thought, as you probably figured out, I was just going to use the bathroom "however," that is, wherever and however it happened without even worrying about making it to the toilet.

At that point, I started laughing so hard I practically did use the bathroom "however"!
