Downclimb to the first rap off the Tooth in winter. There's a guy standing there in lightweight polypro, shorts and approach shoes just standing there shivering uncontrollably with a rope hanging off the ledge. We ask where his partner is. He gestures down the face. We ask if he'd like to rap with us. He agrees. I thread a rope through the slings and hand him the ends to tie while I flake one rope and my partner flakes the other. I turn back to see him just standing there shivering. I ask and he responds that he hasn't done that before. I tie and we rap. Half way down his partner appears from the sunny side of the face, equally hypothermic. We assist them down to the pass. As we are leaving, I hear the dude we saw first say something to the effect of, "You're the experienced one, you should have led that pitch."
