G
Give him an inch and he'll take a yard.
Interpretation
Some greedy people always exploit the magnanimity of others.
Comments
At times one's benevolence becomes a painful experience, when it is misinterpreted by a selfish person who is not worthy to sit in a train or bus, and after some time, he will encroach on more space. Hence, it becomes necessary to help only those who deserve it.
Origin
This proverb was first recorded in 1546, thus, "When I gave you an ince you took an ell," highlighting that greedy people take advantage of one's magnanimity and kindness.
