Someone once insulted a very pious person.  The community wanted to put a ban on the man, but the pious person would not hear of it.

“We must punish that man, not merely for your sake,” the pious person was told, “but to prevent the insulting of others.”

“On the contrary!” exclaimed the pious person.  “Let people learn from me not to let insults bother them.” ~ Sefer Chasidim as quoted by R’ Zelig Pliskin
