为何你那么伤心呢？
笑着笑着我绝哭了。
明明是快乐的我眼里只有哀伤。
明明这是我当初要的，我绝觉得不快乐。。
那道我要得不是我想的？
我开始问了自己。

I believe that is always what every1 is thinking... Always thinks that now what u achieve is what u wan ... But u think back, actually i am in miserable statues is this really what i wanted?
Only after u know what happen then u regret ... U can put words that u dun bother ,u dun care , u wont get angry nor sad but how many times u did those in actions instead of words ...

At the end did u hide behind some1 or sth and start crying? Is ur heart breaking everytime u saw that? Is ur heart dripping of tears and blood for u while u still need to smile in front of others acting nth happen?
