Rain, Rain (don't) go away

These photos are a couple of weeks old from a morning we drove Chris to school since it was pouring so hard, and I had forgotten about them until just now when attempting to clear my full memory card. I'm so bad at having no space on my camera. Anyway, everyday lately Ryan for some reason has been requesting that I sing "Rain, Rain, Go Away." I find this confusing for three reasons. 1) I'm a horrible singer. 2). I think I sang it just once in passing. 3). He seems to have no problem playing in the rain.
