Sign of Fall

I'm not sure if this is funny or a cause for concern.

I don't know about you, but in the summer it is either bare foot or sandals for me and the kids. The other day was a little chilly and Dallin walked up to me and said, "Mom do you have mud on your feet?" I looked at my feet and said, "no." Still puzzled he says, "what's all over your feet?" I looked at my feet again and realized what he was talking about. "Those are my brown socks!"
