Dear Michael,
Thanks a lot for your last letter that I have received not long ago. I am sorry that you had to leave your school when your family moved to another neighbourhood.
Believe me, I know how you are feeling now, because I went through a situation like this two years ago.
Though, I think you exaggerate this problem, because I know it is not too difficult to make new friends at a new school as you think. That is what I like most, - everywhere you go, you can find a bunch of people that are friendly and easy-going. That was occured to me when I acquainted with my new schoolmates.
My new school is situated near a large lake as you know, and that makes going there even more exciting. As you can imagine, we have a lot of fun playing soccer and volleyball in spring and autumn on the banks of the lake. Winter is a time for hockey and skating. Of course we do these kinds of activities after our homework is finished.
So, don`t be so upset, I am sure meeting of new friends at your new school is just a matter of time. It won`t be long untill the right people come along !
Yours sincerely,
Nick
