how does the TT make a new friend?

The TT made a new friend when he saved her life. He saved her from drowning.

That day, too, I made a friend - of a sort. It happened that, as I was watching some of the little people bathing in a shallow, one of them was seized with cramp and began drifting downstream. The main current ran rather swiftly, but not too strongly for even a moderate swimmer. It will give you an idea, therefore, of the strange deficiency in these creatures, when I tell you that none made the slightest attempt to rescue the weakly crying little thing which was drowning before their eyes. When I realized this, I hurriedly slipped off my clothes, and, wading in at a point lower down, I caught the poor mite and drew her safe to land. A little rubbing of the limbs soon brought her round, and I had the satisfaction of seeing she was all right before I left her. I had got to such a low estimate of her kind that I did not expect any gratitude from her. In that, however, I was wrong.
