Once in a while，we see that a person in the film changes the character all of a sudden after he witnesses an unexpected matter or other cases. Do you think it really makes sense in our daily life? Just talk freely.

Of course it makes sense.all the stories come from life or imagination, but most are far more abstract than that. it seems to happen all of a sudden,but in the real story it usually takes a long time to change a person's Character. however,time is limited for a single film, so the director can't cost a long time to describe why,how and when he changes it…It's reasonable if only you dont feel weird about the change~

Yyes, I so believe that a major-great-event could change someone overnight completely, depending on how serious his loss Was.
fortunately or not, such an incident didnt yet knock on my door, that's why I always feel immature like a damn kid. FML

lemme tell ya a stroy Ive seen news reported, about a man was once talkative, humorous and inthusiastic, but talk no more (maintain totally silent) after the 512 earthquake, and he formed a habit by, of leaving a botl of water at the bedside before going to bed... OMG

老天爷给了你一个特定的属性，你还要改它？“人定胜天”只是一个愿望

哇咔咔，可以教我学英语么

为什么要改呢？
性格只要找到适合它的路，就能为人类做出巨大的贡献。

更多的精力应该花在寻找最适合的道路，而不是改变它。
