Dear Grandma,
Thank you for the new shorts. They are cool! It's hot in Beijing. It's sunny too. I can wear my shorts and T-shirt. I have a new jacket. My old jacket is too small. I want to buy a hat. It is fifty yuan. It's too expensive.
What's the weather like at the farm? Is it warm? How many new ducks are there?
Love
John
