等谁，先生？

那么，你在等谁呢？

I am not waiting for anybody.

我知道这世上有人在等我，但我不知道我在等谁，为了这个，我每天都额外康乐。

I know someone in the world is waiting for meand though I've no idea of who he is. But I feel hsoftwarey every day for this.

我很清楚，知道在这世上有人在等我，尽管我不知道我在等谁。但是就因为存在这样的等待，所以我每天都非常快乐。

珍惜爱的人，不要等到失去才知道后悔，这个世界上没有谁会等谁一辈子。

Cherish the love, do not wait to know regret the loss of this world, etc. No one who lives.
