No Moms and Dads Allowed

I don't know how it happened, but my son is becoming a teenager. So much fun! (Not)

This morning he came in our room and showed us this picture he drew. He asked Dad to read it. "No Monsters?" guessed Brad.
"No!" protested Noah.
Brad laughed and tried again "No People?"
Noah still was not satisfied, so he turned to me. I took a few guesses, trying to figure out what he was trying to express through his artwork and it finally came out.
"No Moms and Dads in me and Amalie's room!" Noah exclaimed.
"Ohhh."
I just had to laugh. I think it was revenge since earlier he had locked Amalie out of our room, so I banished him. He sure showed me!
