I am going rock climbing for the first time next weekend with my kids.  I'm not too sure about it but maybe you can help me feel better.
Sure! Just remember that accidents are more frequent on the climb down than the ascent, so be careful!
Oh, good tip. I'll remember that.  But how do you get down if I suddenly am too afraid to climb?
You'll probably take another route down - it's very rare for a climber to downclimb.
