Misunderstandings are certainly horrible

A close friend scolded me yesterday due to a misunderstanding that we had. I feel awfully bad. It was purely a mistake and was unintentional. Now, he is mad and annoyed at me. All i could do, was apologize. Whether or not he accepts my apology, that's another question. What i'm sure of, is that our friendship will never be the same, for i will never ever forget this incident. It will be etched in my mind always, whether i want it to be or not. It will always bug me.
