I walked into my sister's kitchen and found my nephew, Dewey, having a snack.
"Where's your mother?" I asked.
"She said she was going to have a shower. Just a second, I'll see."
Dewey went to the kitchen tap and turned the hot water on full blast.
An indignant yell came from above.
Dewey calmly turned off the tap and said, "Yep, she's in the shower."
