In reply to UKC Articles:
I have one partner with a bizarre habit: when poised beneath a crux section on lead, he sometimes insists I take photograph. But I say, "it won't come out, all I can see is your arse and there's too much backlighting". Response "Look I'm not going on until you take a photograph so just take one anyway!'
But maybe this is not so strange. When I am on lead at such moments I often seek assurance from my belayer - "Are you with me?". Given that all the rest is in order (knots, gear etc) finally what we need is that critical knowledge 'I am not alone' - idem for so many other trials of life
