The large "box" you see Sam and Levi playing in is actually the shelf that belongs in our bedroom. We had left the back off so that it didn't cover up our thermostat control, but the shelf wasn't sturdy enough without it. So yesterday I brought it out to the living room to finish up. I figured Sam would have a great time helping me nail (which he did). I put on some music to help us work, and the shelf was christened "the dancing box".
