Anger can be a tricky thing. Someone can do or say something to you that sends a trigger of defense to your mind. When this happens many people lash out at the individual without thinking.

In relationship, if you continue to do this without checking inside first, you will end up having, at best, a tumultuous relationship.

I have a best friend who has a best friend who dislikes me for no real reason. She has never spent time with me nor even given me a chance. She simply makes fun of every choice I make, and my best friend thinks it is funny. He thinks her comments are funny. Recently she had a party and told him I could not be his +1, which completely unnerved me. 

When I discovered this I lashed out at my friend. What I realized is this: I wasn't angry with his best friend as much as I was that MY friend didn't sound like he had any compassion for my feelings. I felt he dismissed the fact that I felt she was being unfair. When I was able to go inside and be honest with myself and with him, I felt completely different.

I want to encourage you to be clear about what you are angry about when arguing with a mate or a friend. Remember that you bring to the table your entire life or relationships when you relate to people. You argue with a partner and sometimes you are simply arguing with your mother or yourself. Be sure you know how to communicate that to the person you love.  I assure this will make for deeper love and understanding.
