After the monster insisted for a bit, then took my hand and physically dragged me out of my chair, I relented and went to play cars with him.
Me: *picks up a car*
LM: Maybe Monster will drive the Renault.
Me: *picks up another car*
LM: Maybe Monster will drive Alfa Romeo.
Me: *picks up third car* Can I drive the BMW?
LM: Maybe Monster will drive the BMW Z4 *tries to take car out of my hands while refusing to let go of other 2 cars*
Me: *Stands up to return to my chair*
LM: *Maybe Mama will sit on the ground and play with cars!*
