Give him an inch and he’ll take a yard.
得寸进尺。
If you grant some people a small favor, sometimes it only encourages them to take much more than they are offered. Such people should be avoided. Instead of showing gratitude, they will try to get more from you. And the more they get, the more they want. There’s no satisfying them. As the saying goes, “Give him an inch and he’ll take a yard.”
如果你答应帮某些人一点小忙,有时只会鼓励他们索求无度。这样的人应当予以回避,因为他们不但不会感恩,反而会向你要求更多。他们所得愈多,贪图就更大。谁也无法满足他们的心。俗话说:“得寸进尺。”
