Hi, Steve!
Thanks for your letter, I was really pleased to get it. How're things?
You said you've just moved to another district of the city and that makes you nervous. You will have to change school and you won't be able to see your old friends as often as you would like to. Cheer up! Think about the good points. Even if it seems to be difficult, you can make friends with many other people. Don't be shy when you come to your new class. Other children will be quite friendly with you. In a couple of days you will get used to everything. Just don't worry.
Sorry, have to do my homework.
Write back soon!
Best wishes,
Vlad.
