My dear friend：
Hello!
I want to share my picnicking experience in the park on sunday with you,because I was so happy and really had a good time there.
In the morning,it was sunny,so my parents and I brought some sandwiches and drinks and then drive to the park.We sat on the grass and had the things we packed together under the shining sunshine.
I really enjoyed it,and hope you were there with us.
Yours sincerely
