Rocket ships

Henry is very interested in rocket ships and space.  He saw a picture of the space shuttle yesterday (I should say, he knows all about it and has seen many pictures of it before) and was asking about where the cockpit was and so on.  This morning he announced that he wanted to ride on the space shuttle today and sit in the cockpit.  I said the cockpit is the only place to be in the space shuttle, explaining that there are no passengers and just a few seats for the astronauts.  He thought about that for a while and then said, "There are only three seats, Mama, so you and Daddy can sit and Agatha and I will stand."
