Lisa suggested this essay about vigilance:
“Vigilance is alert watchfulness. And as a climber it is paramount to be vigilant, not only for my own safety, but for the safety of my partner. Through the act of belaying, or protecting a partner with the rope, is when I am most watchful.”
“Belaying is a love hate thing for me. On the one hand I love being in a position to encourage and coax my partner up. On the other I have intense feelings of impatience, and become critical and think, no KNOW, how much faster things would go if I were on the sharp end, only to climb up and realize first hand the challenge my partner faced on lead.”
