Dear Mark, Thanks a lot for your letter. I got it two days ago. I was a great surprise. I'm sorry I haven't written for such a long time. I have been very busy at school. I will arrive for you on airport anh I hope that you will stay at me some days. We will go to the cinema or theatre and we will go sightseeing. You should take a warm jacket and warm boots, because the weather is changeable. Today is sunny, but it is often rainy and cloudy. I am very happy that we can meet again and I can not wiat longer. I hope you will have a good and safe travel. Bye for now. Say hello to your girlfriend for me. XYZ
