Jesus was reported to have said, "A soft answer turneth away wrath."
The Buddha allegedly advised, "Avoid load and aggressive people."
For me, it depends on the circumstance.
If they are strangers or acquaintances and I've done nothing to trigger their behaviour, I ignore the remark.
If I've made a mistake, I apologise and do my best to correct it.
If it's someone in the community who is habitually or frequently rude I avoid them.
I can't remember an instance when a friend was rude.
If it's my husband (rare,) I ask what has upset him and listen carefully.
If it's due to something I've said, done or omitted, I repair the mistake and make amends to the best of my ability.
If not, I ask him what he needs and how he could fulfil it.
Rudeness is caused by anger.
Underneath anger is pain, shame, or fear.
When we know the root need that is not being met, the solution can be found.
One thing I've noticed is that both kindness and rudeness tend to be "catching."
So we can each make a difference by avoiding being rude when we feel angry or irritated.
