Akito is your best friend. Although sometimes he can offend you with his rudeness, he is quite a good friend. You study in the same class and sometimes go out together. He's into music, and you almost love rock climbing and mountaineering. You do it pretty well, so you can climb not very high mountains without a guide, or with a guide who watches from the foot of the mountain. And of course you want Akito to try it. And so, after two weeks of persuasion, he agreed, but not to a very high mountain. You tried to prepare everything so that everything was as safe as possible. You even bought Akito a special jacket (with his money, of course). At the beginning of the climb, everything was fine. Akito only had a slight headache, but you assured him that it was okay. And when you were only a few hundred meters from the top, you suddenly felt terrible and you and Akito stopped at some more or less safe place. You thought it was Akito who would feel bad, not you.
"Are you sure you're okay?... Maybe we should go down.."
