If you are being the best person you can be, if someone has a problem with you, it is just that: their problem. Some people don't stop to think before they speak. I've learned while dealing with the public that if someone is rude or unpleasant to you they may be having a bad day or just may be a negative person. Really nothing do do with you personally. They were an @$$ before you came along and will be after you are gone. Same applies to other drivers.

The next time someone insults you smile and thank them for their insight. That will make them wonder. lol
