Mary, you were positively radiant. (15 years younger than whom?)
McGrath, you could back up yet another step, and ask why one should need to scrub at all.
I have this body scrub I bought that has sea salt as the abrasive. Maybe sugar crystals are smaller, or something. I've also thought it would be nice to have socks that would have warm sand inside to get rid of spare callus on feet. Wouldn't it be nice to have the feel of walking on a sun-warmed beach in the middle of winter?
