We never know what another person is going through. We don't know why they snap at us or are rude. They may be that way all the time but we don't know why. What are they going through at home. Is someone they love sick? Are they hungry and working to feed their children? Do they have bruises you don't see? Today they may have gone to the doctor and found out that they only have a limited time on this earth.
Before we judge or snap back in anger, stop and remember a time when you were in a low time of life and have some empathy.
