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
Sometimes, you actions do affect other people 
Sometimes the people with the worst past 
The most treasured gifts in life 
Always tell people how important they are
