Our "normal" routine for wake up time (in the morning and after naps) is that I get Peter first, then Aaron. While I am getting Aaron ready Peter is free to play in his room or downstairs.
This afternoon after I got Peter up I saw him go into his closet and get the noise-canceling headphones that we had gotten for the boys when we took them to the Monster Truck show. I didn't think anything of it and went about my business changing Aaron's diaper.
Five minutes later Aaron and I came downstairs to find Peter and Rusty (our dog), sitting in the middle of the living room floor, each wearing a pair of headphones.
Peter looked up at me and said, "Mommy, life is so good when Rusty and I can't listen to you."
