I know that when I pulled your hair it hurt you physically and emotionally. I'm sorry now and shortly after it happened. I was just playing around but I wanted to let you know that when you yelled at me it hurt my feelings also. What hurts the most is that I told you about your lack of an apology and you still didn't apologize.
I don't want to blow this out of proportion but any apology would have been great coming from you and you didn't offer one. do you know why it didn't? As you read this, please don't let situations get the best of you. Forgive and move on because life's too short.
