Hi Artyom, I am writing to you from New York. How are you? Everything is fine. It is very interesting here. I'm sitting at home right now and writing you this letter. I study here at the best college. I study very well. There are only two months of summer vacation, but I rested very well. In the summer, I worked part-time at various jobs. There are a lot of them. I really miss you. I’m not friends with anyone here. In June, I worked all month for part-time jobs. In July, I went for walks to various beautiful places and places of interest. And he taught the rules and formulas so that later it would be easier to learn. I hope you are doing well too. I hope my letter will come quickly. Write me how you are doing. While Artyom is your brother ...
