It’s no use letting anyone make you so angry you stress yourself.
A better philosophy instead of turning to frustration I offer you this analogy; think of your daily interactions on your path of life as a drive on a lovely mountain road driving with the wind of voices whispering past you. On your journey you may come across people rude or irate toward you in some way or even irritating you with their very manner.
In your imagination stay on your scenic mountain drive, and this person turn them into a bug flying past or into your windshield. You won’t notice them while driving as they are a tiny speck on a broad protective shield and you need to focus on the road ahead. That’s the simple trick to it, always remind yourself there is a broader scope of your life pushing you forward and don't bother about the little bugs along the way.
