Compassion

Here's what I know. You are not the only one who feels the way you do. Every emotion you have had someone else has had as well. The key is to remember this when dealing with other people. It's so easy to judge that person who has said something you didn't like or made you feel small and insignificant. But the fact is they have felt the same way. Someone has belittled them or hurt them in some real or imagined way. Either way you have a choice. You can get angry and strike back or you can stop and ask yourself  what is going on in their world that has made them angry, bitter or just plain mean. I assure you they weren't born that way.
Someone has hurt them just like you felt hurt when they did or said the thing that made you feel bad. For your own well being, take a moment to think before you respond. Only you can choose to be angry and strike back or not.
