Today A and I were walking to school to pick up J. A said, "I'm Batman, and you're my boss, because batman has a boss to tell him what to do".
"Okay", I say.
"I love you boss."
"I love you too batman."
Then a few minutes later as we crossed the street, he held my hand and said, "Batman always holds his bosses hand to cross the street".
Later, getting ready for bed, batman became Jeepman (because his batman pj's were dirty, but his jeep pj's were available).
