He gets a fantail goldfish for his forty-seventh birthday, and he can't decide whether he's more amused or annoyed at the standing joke.
His PA swears she has nothing to do with this, but he suspects she actually helped his little brother sneak the aquarium in. In the end he just offers the animal a cold-eyed stare before going back to his business.
At least the goldfish is quiet, and he finds himself furtively glancing at it when he's particularly bored.
Perhaps he can tolerate a pet. After all, he endured his brother for the better part of his life.
