“ It takes just as much training to get along with people. Only, training by yourself in the mountains won't do you any good. You need to surround yourself with others. As you get to know them, of course you take the chance that you'll end up hurting them, or they'll end up hurting you. One of those things might very well happen. That's the only way we learn... about others, and about ourselves. ”
