My MIL received some flowers from my FIL for their anniversary. Diego took the box they were delivered in and in all seriousness , cut a hole in the side, stood it on end, and pronounced that it was "a potty for him to go pee-pee in the night to put in his very own room."
We all laughed at this, telling him sorry, but he couldn't do that. He was not amused. He wasn't kidding.
"When will I EVER get to have my own toilet in my own room? Don't tell me I have to wait until I'm a GROWN UP!"
