Dear Sergio,  
I was very glad to hear from you. I haven't written for ages because of my sport activities. I took part in a serious completion so I had not much free time.
Tell me, please, are you really in New York now? I want to know how you have got there. Are you travelling alone or with your parents or friends?
We are very worried about you because you are a really troublemaker. You must write us a postcard every day to tell us about your everyday events. Well, what is the best thing about New York for you? Are there many beautiful buildings or maybe you made friends with interesting people there? Have you got any plans for the evening? Where are you going to go and what to do? Oh, we wish we were there with you. It would be great!
That's for me for today. I have to go to a school club.   
Best regards to your new friends. 
Write soon.   
Yours Happy (твое имя)
