Ответ:
Dear Michael,
Thanks for your last letter that I received the day before yesterday. You wrote that you had quarrelled with your old friend, and now you're feeling as if you were wrong when you accused your friend of something. You also wrote that you haven't slept well since that day and you have been feeling as guilt is gnawing your heart.
I don't know which of you was right in the situation that led to argument. But you know I faced a situation like this before. I had a terrible quarrel with my school friend and then I didn't know how to resume our relationships. Then I realized that the first thing I had to do is to calm down my own nerves. When I did it, I found a couple of ways for dealing with that issue. I chose to phone my friend and explain in a polite, soft manner what I meant when I was arguing with him yesterday. I clarified why I had got so irritable and why his words seemed to me so abusive.
As it was done, I felt much better and my friend also recognized that he felt relieved after listening to my arguments. I apologized for my improper behaviour, and he did the same. So, everything was decided quickly!
Here goes my advice, - don't waste your time, just call him and try to tell him how sorry you are and believe me you and him will definitely find ways to sort out this problem. I'm finishing now.
Keep in touch.
Best wishes,
Dennis
