I walked into my sister's kitchen and found my nephew, Mitch, having a snack.

"Where's your mother?" I asked.

"She said she was going to have a shower. Just a minute, I'll see."

Mitch went to the kitchen tap and turned the hot water on full blast.

A sharp yell came from above.

Mitch calmly turned off the tap and said, "Yep, she's in the shower."
