Why?

We seem to have arrived at that phase of development when just about any statement is met by Charlotte with the question why. In many cases this can be answered by asking her why she thinks x is the case, but a bunch of the time she is simply asking legitimate questions about the workings of the universe, which we feel compelled to answer. Daddy covers questions of atmospheric science, physics, and astronomy, while mama is in charge of biology, sociology, and chemistry. I am seriously curious  what on earth happens to parents with less than 3 graduate degrees between them at this stage! She stumps us all the time. God bless the Internet.

Mama, why can't I hear you when my ears are under water?
