One of my boys recently turned 9. My wife said she caught him today wearing the same undershirt to school (and to bed) for several days in a row. "Disgusting boys!" she said.
Funny, he told me something really sneaky the other day, "Pssst... Dad, if mom ever makes you take a shower..." Just that sentence alone made me chuckle on the inside from his perspective. "...If mom ever makes you take a shower, you can just take off all your clothes, wrap yourself in a towel and put a little water on your hair from the sink. She'll never know."
Kids are great, and sometimes little boys can get a bit smelly. Big boys can too. Fortunately, I like to take showers--and use soap!
