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
Some people think that to be strong is to never feel pain 
Respect people’s feelings 
If you allow people’s cruelty in your life 
Don’t worry about the people who hurt or hate you
