The other day I noticed some scabs around Blair's waist, as if he'd been cut (or scratched by a cat). "What happened?" I asked. 

"It's from running," he said. "Friction with my running shorts." 

"You need some Glide," I said. 

For those non-runners, Glide, or BodyGlide, is an anti-chafing balm. It comes in a deodarant-like tube and you apply it wherever there may be friction with your body and garments. Most people put it under their arms, around their waist, around the jog bra area for women, over the nipples for men (bleeding nipples are no laughing matter), on your feet... I even put it around my wrist so my watch doesn't chafe. It's a standard product, used by the majority of runners. That or vaseline, whatever works. 

So back to Blair. "You need some Glide," I said.
