情义

有人曾说 “你跟人讲情义， 十个会有九个当你是傻子”。

I never thought this would be true in real life, and then I only got to taste the bitter fruits for not believing such a good teaching.

You whole-heartedly do something for somebody, then the person does not really appreciate your efforts. Instead, he/she will start to suspect you have some vested interest.

When they reap the benefits from your efforts, they will only consider that as their own merits.

看开点儿啦。。。
