My brother’s terror and my favorite, when he was 3 he climbed over five baby gates and up and down the stairs, and somehow climbed up and gotten the good bread knife off of the top of the bookshelf it was stashed on top of. He charged into the room and waved it at us, sternly lecturing us that This. Is. Not. A. Toy. He’s 15 now and I don’t know how he’s survived this long.
