Dear Paul,
Thank you for your letter. I haven't written for a long time because I was very busy. Now, I am writing to you just because I miss you!
Unfortunately, I have bad news. When I was coming back home from your place, I had some problems. I ran out of petrol. I had to stay in the middle of nowhere. I was trying to call for any help for about an hour. Finally, I met a man who gave me some petrol. I lost almost two hours because of this situation.
I also have good news. I have a brother! My parents and I are very happy. He IS one month old and he is a really beautiful child.
I am glad that we could spend a few days together.
I hope to see you again in a short time.
You should visit me when you come to Poland. You must meet my family.
Love,
XXX
