Dear David,
How's it going? Let me tell you something about my last weekend.
Last weekend, I went to my grandma's home in the countryside with my parents. I helped grandma do the housework and picked fresh vegetables in the field. The vegetables there were so nice! In the afternoon, my parents and I took a walk around the village. The air there was very clean. I had a really good time that day.
What did you do last weekend? Write to me soon.
Yours,
Li Hua
