People who are rude deserve to be responded to. Maybe the next time they will think twice before saying something hurtful to another person.
I work with someone who is rude. When he makes a rude comment directed at me, I don’t respond. Then the only words left to hear are the rude ones left coming from his mouth. ~ Janelle Kurtz
There is never an excuse to be rude to anyone. You see the true colors of a person when they are rude. Their mask slips they show you who they really are. ~ Susan McMahon
We all have feelings for others 
Let go of the people who dull your spirit 
People will never forget how you made them feel 
Spend time with the right people
