I didn't actually believe that they hadn't done anything else for 5 hours while waiting for the climb and thought that they might have gone off, done something else, come back, etc. I was expecting clarification and was quite shocked that they really had waited! Still - I guess like it says earlier in the thread, there are all sorts of people in every walk of life.
I guess I just don't know anyone personally who is like this...
