Someone in this house filled our bathroom sink with toothpaste.
Someone also decided it was "an accident."
After being told that she had to clean it up and lose out on her treat tonight, she accepted it surprisingly well... and hmphed a little.
A few moments later, she said, "Oh, I'm not your daughter. I'm a teenager named Ella. I hear you're having a trouble with the kid..."
I confirmed that we were, indeed.
"I have an idea on how to deal with her."
I asked how.
"I'm just going to put her in the garbage."
