A colleague of mine recently got a lawsuit against one of her twin children. The elder one was already in jail, and now the 2nd a public indictment. She is trying her best,using up all her energy and money plus credi-card debt,to save her child from being sentenced. Everytime I tried to say something consoling her, will see her watering eyes. Many other cases I have to confront in my daily job. Their lives have nothing connection to my job nature, but I still response them by giving some suggestion and opinions, which may sound stupid or not be any help at all. Human nature, the most difficult problem to deal with, yet the most interesting course to study.
