Thanks for your letter. I was so glad to receive it. I'm sorry that I haven't written for a while, but I've been really busy.
In your letter you told me that you've had an argument with your friend Miranda. I've been in a similiar situation. I argue with my best friend over nothing, but sometimes there are arguments caused by misunderstanding. I tnink you should be the first one to break the ice, it will mean that your friend is still important to you, in spite of the quarrel.
Have you ever argued before?What is the reason of your argument? Is Miranda important to you?
