[du-] Dumbledore is in the [4] bathroom of the [-(e)i] beach house by the bay where he is trying to 对 correct the rusty showerhead pipes. He wears beach shorts and a straw hat instead of his usual wizard attire, and stands on a 又 folding stool that is in the bathtub. He bangs a magic 寸 caliper against the rusty pipe to 对 correct it. Just doing that removes all of the rust from the pipe and fixes it entirely. Dumbledore always has the 对 correct idea on the fastest way to fix things, even when he is on vacation at the beach house.
