Like Dust

Every day when we daven we ask Hashem ולמקללי נפשי תדום ונפשי כעפר לכל תהיה - To those who curse me, may my soul should be silent and may my soul be like dust to all. Explains the Chasam Sofer [Perek Kisui Hadom]: Not only do people TRAMPLE on dust and the dust does not respond but dust also produces FOOD that sustains the world. Even when people are mean to you, you should still be generous with them.

Kill 'em with kindness:).
