That's always been an inspiring story for me. Later I became interested in the last part of the story. Sul is crying and crying for her granddaughter, then someone asks her a question and she immediately stops crying. Usually our emotions tend to linger, so we often don't do justice to one situation because we're bringing our emotion from something that happened before. Maybe you have something difficult going on with your spouse, then you're driving to work and someone cuts you off slightly, and you give them all the anger that you have built up for your spouse.
People actually get out of their cars and shoot each other.
Or something is difficult at work, and you go home and ignore your kids or get angry at them. So I was very impressed that Sul didn't linger in her feelings or let them affect the situation. In fact, she used them to teach other people. It just says she grew up, married, had a family, and everybody came to her and found her very helpful. Then you get this story about when she's a grandmother.
