Dear Grandma,

How are you? Thank you for your new sweater. How beautiful is it! I like the colour—orange very much.

Now I am writing at my new school to you. It's a nice school. Trees are green, flowers are red and yellow. We have a music room, an art room, a computer room, and a library. I like the playground very much. It's so big and we can play football there.

Oh, it's four o'clock in the afternoon! It's time for P. E. class. I have to stop here. Welcome to my school and welcome to my home!

Love,

Mike
