My new box house

Daddy came home the other day with a big box and then he chopped it apart and it was a house. He said his daddy (that's my grandad) made him a great big one when he was little and the girls at work told him he should make me one with a box they had that no one needed. Here is our house. It is fun but Jack does not like to play in it. Not even if you peek at him through the window. He still does not think it's fun. I chased him and asked him nicely to keep playing but he very firmly told me no.
