What did Mary ask John to do?

W: Is the baby with you, John? He’s not in the kitchen.
M: He isn’t here, Mary. Perhaps he’s upstairs.
W: Please go and see... He’s very quiet.
M: All right, I’ll go and see... Mary, he’s not in his room.
W: Is he in our room?
M: No, he’s not there either.
W: My God! Where’s he then?
M: Oh, he’s here, in the washroom!
W: In the washroom? What’s he doing there?
M: He’s cleaning his shoes with your toothbrush!
