Question

i have to write a letter to my brother, who is not happy in the new boarding school.

Answer 1

I am providing you with the content, please do inform if you want the format too:

Dear ABC,
I hope this letter finds you in the pink of your health. We all are fine here. I got to know from your last letter that you are not happy with your new boarding school, though the reason you wrote, that you are not able to make new friends, made me a little worried.

It would surely take some time for you to adjust in the new surroundings without us. You should understand, that nothing can be achieved if you are not brave and strong enough. You should try to talk with your classmates and make friends with them. Running away from the problem is not the solution. You can also tell them about yourself and know about them too. Maybe they would start being friendly with you.

Take care of yourself and write to us as soon as possible. Mom and Dad miss you a lot.

Yours lovingly,
XYZ

HOPE THIS HELPS :)
