“Armrest's fixed, and you're graduated.”
Pick the Dunsabian family and this is who raised you. He keeps the ship's air fit to breathe, and would sooner mend a thing than talk about it.
At your graduation he spends the speeches mending a loose armrest, and stops only to clap. If he hands you a spanner on a cord, wear it.
