Did you use soap?

I am going to share a tidbit about one of my children, who shall remain nameless. My kids are at an age where they can handle bathing or showering themselves but still need some reminders about using soap and hitting all the really important spots. One day not too long ago a still wet but already pj'd boy appeared after his shower. He had finished too quickly so I gave the inquisition...did you wash your hair? yep. with shampoo? yep. did you wash here and there? yep. yep. yep. did you wash your butt? yep. did you use soap? nope.
Hmm......
