Dear Lingling,
Last Sunday, it was September 9th. I had a good time. I had a picnic with my father, my mother, Aunt Li and Uncle Wang. We went to a park by car. There were lots of fruits on the trees. How beautiful they were! They were sweet and fresh. We helped the farmer pick the fruits. We came back at half past five.
Love from,
John
