Colleen

“You’re always on that old Twisty. Try something new. Try the monkeybars. Show me a trick.” His sisters, Colleen and Marie, were on them, climbing and swinging like... well, like monkeys. So, to please Grandma, he went on the monkeybars and slipped while hanging upside down and fell and broke his arm.

One of Finn’s two sisters is named in his childhood memory.
