I was cleaning my daughter's bedroom today, and didn't want Petey to come into the room, so I left the door open a crack so he could see me, but I told him to stay. So he laid there watching me from the hallway. He SO wanted to come into the room with me. Finally he found the perfect excuse to enter. He got his tennis ball and rolled it into the bedroom, then would have to come in to retrieve the ball! And once he was IN the room, he thought me might as well STAY in. So I'd grab the ball and throw it out into the hallway and he'd roll it back into the bedroom AGAIN. And again. And again. lol.
