You can never really know why others act as they do. If you’d had the identical programming and experience, you’d behave exactly as they do. For instance, If someone’s driving seems erratic or dangerous, they could actually be reckless and inconsiderate or responding to an emergency, sick or overcome with grief and sadness. If you feel you must let others know how you feel about their behavior, do it kindly with a willingness to understanding. That way you don’t add negativity and heaviness to their load, and you….
Spare yourself, too.
