Round & Round

Nathan: "I want to go to his house."
Me: "His who?"
Nathan: "He has a sandbox."
Me: "Who is he?"
Nathan: "He is him in the house that has a sandbox!"
Me: "Where is his house?"
Nathan "His house is his home with the sandbox!" (While he looked into my eyes pleading for me to just know.)

This continues for several minutes: Round & Round.
At this point, (feeling badly that I'm daft) I think about Tessa's friend who is over....

Me: "Is He Ellie's brother?"
Nathan: "YES!!!"

Phew!
