    陶谐，字世和，会稽人。弘治八年乡试第一。明年成进士，选庶吉士，授工科给事中。请命儒臣日讲《大学衍义》，孝宗嘉纳之。

    正德改元，刘瑾等乱政。谐请以瑾等误国罪告先帝，罪之勿赦。瑾摘其讹字令对状，伏罪乃宥之。帝命中官崔杲等往江南、浙江织造，杲等复乞长芦盐引。谐再疏争，皆不听。谐当出理边储，以工科掌印无人，请俟行日遣官代署。瑾遂中谐，下诏狱廷杖，斥为民。旋榜为奸党。又诬以巡视十库时缺布不奏，复械至阙下杖之，谪戍肃州。瑾诛，释还乡，其党犹用事，竟不获召。

    It was a bad time for me. I was low emotionally and tired physically. Probably because of this I hadn't shaved for a few days. Also, because I had been doing some repairs at my daughter's house, I was dressed quite scruffily(不整洁地). Boarding the bus to go home I saw it was almost full so I found a rail(扶手) to lean against.

    That's when a young woman, sitting with her child, stood up and offered me her seat. ‘Wow!' I thought. Out loud I said, “Do I look that old and tired?” She replied, “You look like you've had a tough day.” I thanked her sincerely and stayed standing.

    A moment later a man rose from his seat at the back of the bus and made his way towards me, walking past several people on the way. Then he told me about his addiction(毒瘾) problems, asked my advice, and just chatted about life for a few minutes. Then he went back to his seat. Very random!

    Watching him go, I also looked at the bus-load of people between me and his seat. He hadn't chosen to talk to those strangers. He chose to talk to this stranger, for whatever it meant to him and whatever comfort it brought him. Why?

    That's when it occurred to me. I must have looked like I had been where he was. I probably looked like a man who would understand a difficult life. I was humbled(谦卑的) and encouraged at the same time by the realization that even when we are at our lowest we can still help others — if we look like we might be able to meet them where they live or walk a while in their world.
