Declan has been playing recently with these battery-powered Thomas the tank engine tracks. Earlier today, I set up a track that ran pretty close to the large plastic box that contained all of the left over track. On the first run, the train hit the edge of the box and fell off, so we moved the box and everything was happy.
Just a few minutes ago, Declan came downstairs into the Kitchen and requested that Tara come upstairs. I suggested that I could help, but Mommy was required. He took us upstairs into his room, where he walked across the room, and gesturing to the box (which was back in its original position) questioned: "Who put this box here?" He continued "See what happens: the train gets stuck if this box is here."
Tara had to confess. Hilarious.
