U Day

This morning my son showed up to my bedside at 6:05.  He was completely buck naked.  He said, "Is it a Family Day?"  Meaning is it the weekend.  "No Buddy, it's 'U' Day at school.  "Ok then, I  better put on my underwear then,' was his response.  Thank goodness it was 'U' day or my child may have gone to school commando.
