why did the boy throw the clock out the window?

I am lying in bed trying to update my resume. My hubby is putting K to bed. For easter she got a set of space books, and tonight she picked the Moon one. She just turned 4 and could not be more interested in reading. She is getting very good at it. It blows my mind to listen to her read. We have not read the moon book before, yet she reads it with little trouble. I am extremely proud of her. It seems like only yesterday, we were bringing her home, & now she's so grown up. My heart could burst....
