Apparently I need to get out more

Transcript of a conversation in our kitchen, yesterday afternoon:
Robert: Daddy has a lot of jobs. He has Scrabble, and singing in the choir, and the computer stuff*. That’s three jobs! Mummy has just one job; she’s a teacher.
Colin: Well, she’s our mother. That’s a job.
Robert: Then Daddy has four, ’cause he’s our dad… Mummy, if you wanted to do more stuff, that would be OK.
*the “computer stuff” is his actual job
