Dear Kate,
I hope you are having a nice holiday. Tom is staying at the Beach Hotel with his family. The weather is very hot, and they go to the beach every day. Tom is writing to tell you about his day. His brother Sam is swimming in the sea, and his parents are drinking lemonade at a beach café. It looks very fun and relaxing!
Now, I wish you a lovely picnic and enjoy your holiday. I hope the weather stays warm and nice for you.
Write soon!
Best wishes,
[Your Name]
