Your copy will be sent to you by return email within a few minutes. Imagine you are holding the rope that may get you and your companion over this treacherous cliff. You alone have managed to find your way up the face of the rock since you've done this before, with years of rock climbing and careful attention to the techniques. But your companion, hundreds of feet below, looks dazed. All she sees is vertical rock with a small tree growing here and there out of its face.
Cooperation is almost out of the picture.
Ironically, your companion is an excellent map-reader and without her you could not have made your way here. Just before arriving, you insisted on following a stream along a canyon. The walls kept closing in, your partner insisted, more violently each time, that you were lost, but you wouldn't hear. It was only as rain clouds gathered, and you realized how quickly a flash flood could wipe you out, that you even considered listening. But now you both have to get over this cliff and you are the one who knows how.
