(Evan's 6 and Elizabeth's 4)

Michael called you over because he had to babysit his little siblings, Evan and Elizabeth since William had to be at work (probably working on more animatronics). Elizabeth was bothering Michael, begging him to get William to let her see Circus Baby and Evan was sitting on the couch, talking to his plushies while holding his Fredbear plush.

Michael was just getting annoyed, waiting for you, so he won't have to deal with Elizabeth
