Ben, Cecilia and I were walking out of the gym the other day. Ben looked up in the sky, saw a contrail and yelled out "airplane". Ben usually does this when he sees a contrail.
Since Steve was working I said, "Ben, maybe daddy is flying that airplane". Ben then said "hi Daddy" as he was waving his hand in the air. Now I think that anytime Steve is away and Ben sees a plane, he will think that daddy is flying the airplane.
