Nobody did it!

I remember growing up and having my dad pace around the house asking us kids how something got broken. And a lot of times . . . nobody did it. I mean it nobody. He always thought it was sooo strange like we were maybe trying to hide something. But yesterday, I realized, sometimes nobody does do it. My husband pulled up the blinds in the nursery and the window was cracked from top to bottom on the inside. The crib in nowhere near the window, the baby doesn't throw things, the other kids go in there to get a toy or a diaper once and a while. There is no explanation. NOBODY lives and my house now!
