Lily and I had this conversation the other day.
Lily: Mommy, when Nate is in 4th grade and I am in 1st grade, can we walk to school by ourselves?
Me: I'll think about it, why?
Lily: Because then you can get a Sleep Number bed and get a good night's sleep.
Me: Kid, you are cut off from TV, you are quoting commercials!
So, in Lily's mind, if she and Nate could walk to school together, Mommy could sleep in, hence the good nights sleep.
