How to react if someone is angry with you?

One time Brahmin Akkosaka got angry at Buddha, because a man from his clan had become a Bhikkhu. Akkosaka was yelling and insulting the Buddha.

Buddha: “What do you think, Akkosaka? Do your friends, relatives, and guests sometimes come to visit you?”
Akkosaka: "Sometimes they do, Master Gotama.”
Buddha: "Do you then serve them with a variety of food and drinks?”
Akkosaka: "Sometimes I do.”
Buddha: “But if they don’t accept it, who do those food and drinks belong to?”
Akkosaka: “In that case Master Gotama, they still belong to me.”
Buddha: “In the same way, Akkosaka, when you abuse, harass, and attack me, who does not abuse, harass, and attack, I don’t accept your insults. They still belong to you, Akkosaka, they still belong to you!"
