Dear Amir, 

Do you remember last spring when i I left the school and I didn't come back again? I didn't have much time to see you and explain to my condition now.  I have to say that last spring we moved to a new house because our zone (Do you mean neighborhood?  I'm not sure if people say "zone" in some countries; it's not what Americans would say.) wasn't so good. and I have good news for you: we bought a new house.

It I want to explain my new house.  First of all i can express my compliment about I really like my new room and new facilities. It has a big living room and it is a duplex.

If you can and have the condition want to come to my new house, I'll be glad to see you. I think you have my phone number so I will wait for your call.

--I'm so glad you're living in a better place now!  Great job with this letter.
