Dear Aunt Grace and Uncle John,
I am   (write) to tell you that I arrived home     (safe). I got very tired on the train and nearly fell a   and missed my station!
Thank you so much for inviting me to the farm. You were very kind to me. I enjoyed every minute, especially going to the r   where we fished together.
Mum and Dad send their best     (wish).
I will never forget my lovely holiday with you.
Lots of love,
Susan
