Like a lot of people, Melody had a nickname. And like a lot of those with nicknames, hers was based on her last name. And it seems that people with a last name beginning with Mc or Mac always end up with one of the same three nicknames: Mick, Mickey or Mack. And so it happened that two of the McDonald had names or nicknames Melody was Mickie, and Mark’s middle name was Mack. Strangely enough, no one ever called Mark, Mack, though.
