Dear Mum and Dad,

I'm on Grandparents' farm now. Every day it's sunny and warm. There are lots of children on the farm. I play games with them. Now I'm writing the letter in the bedroom. Bill is drawing a picture. Mike is learning French. Lucy is sitting in the sun. Tom and Susan are playing chess in the living room. We are going to milk cows tomorrow, so we should get up earlier tomorrow morning. We enjoy the holiday very much. Miss you!

Love,

Mary
