This morning I got up early and went to school as usually, only to find there were nobody in the classroom because it is Sunday. “How a bad memory I have!” I couldn’t help laughing. Stand in front of the school gate, I began to wonder what to do next. Suddenly a good idea occurs to me. “Why not get together with some good friends for a picnic in such a fine weather?” I immediately telephoned some of my best friends, but they all agreed to join me. About two hours late, we finally arrived a pleasant park with trees and flowers here and there. We really enjoyed us greatly.
