Hello Friend,
I can't apologise enough for nor writing you sooner! I've had a lot of homework so I hadn't time to answer your letter.
I wanted to let you know that I can understand that you feel very lonely after moving to a new town, because all your friends and relatives are still here, in our hometown. I felt the same when I was in a camp last summer. I could suggest you to enter to a sport club and try to make new friends as soon as possible.
Please write me more often and tell me about everything that happens to you!
Forever your friend,
Friend
