Mort didn't bother to keep harping about the water, but he didn't pick the bottle back up either. He'd found the bottle while out scavenging today anyway. No great loss if he didn't come back with it. Not that he'd expected the kid to actually wash with that pitiful amount. If the kid got thirsty, it'd be there. If not, well, he supposed it'd be there still.
"This stuff makes one hell of a nice lather," he said instead, picking up a bar of shave soap. "Only thing is, you need hot, or at least warm, water to get it working with one of these brushes." He picked up a little brush and held it up. "But, doesn't have to be drinkable water, just more or less clean. Filter it through a cloth to get the big crap out and then you just got to figure out how to heat it up some."
He shrugged, throwing some of the shave soap and brushes into his bag. "You got something to carry your share in? Could definitely use it for trade goods. Or, hell, get handy enough with a razor, comb, and scissors, you might even find a little business as a makeshift barber. Ain't like we got better right now."
