Calm down.
Ignore it.
Move on.
No, you did not hear that insult.
Not everything that happens, deserves a reaction from you.
It's not all provocations, that need a response.
Learn to reserve your energy for important things.
Life is short.
Way too short, to be wasted of pent up anger and resentment.
Forgive, and let go of the pain.
Certainly not because that person deserves it.
But because you deserve your peace of mind.
Because you deserve to be happy.
So smile.
Smile, in spite of it all.
For that which doesn't kill you, can only make you better.
Choose to be better, than bitter.
For life is much sweeter that way.
