Sorry, my friend

Yesterday I talked to a friend whom I thought we had something between us which made us have a thorn in our hearts for a long time. I was glad that we could frankly reveal our feelings about each other. From the conversation I surprisingly found that I had hurt her quite deeply in the past although I had no intention to hurt her at all. She told me that not only her, but some people had also be hurt by my attitude. In our sharing, I had an opportunity to look into the 'old me' and I must admit that I could possibly be seen as an inconsiderate, self-centred, and arrogant person which made people uncomfortable or hurt. I am regret that I don't have a chance to meet everyone whom I have hurt to apologize to.
I know that I am not a perfect person and I can't please everybody, but if by any chance you have read this blog and I have ever hurt you, please accept my sincere apology! I really hope that my fault won't stop us from developing a real friendship!
