Dear Simon,

    It's fine today. My family and I are at a park. The man in white is my father. He is standing by the lake and looking at the boats. The woman in blue is my mother. She is sitting on the grass. Beside my mother is Alice, my sister. She is eating cakes. The park is big, and there are many trees and flowers (花朵)in it. We are having a good time．

    How about your weekend? Please write to me quickly.

Yours,

Liuliu
