Difficult one

Auntie Alex plans to come tonight.

• Will Finny come too?
• No. I think he is staying at his Daddy's house.
• But Finny hasn't got a Daddy...
• Yes he does, but he lives in a different place.
• What's his name?
• Donalh.
• That's a funny name! ... Does Auntie Alex have a bed ready for him for when he comes back?

At which Daddy managed to seamlessly avoid a discussion about how sometimes Mummies and Daddies stop loving each other. Tough.
