Today, I dealt with a lot of rudeness.

It sucks. I don't understand how people can be rude. Does it give them enjoyment? Do they not notice they're doing it?
We're called to love. Love everyone, even the people we don't like. Remember what Paul said to the Corinthians?

"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres."

There is no room for it.
period.
