Here is my story.
Once my classmates and I walked around on the dy said anything because of the coming I wished to see their smiling faces! Suddenly an idea struck me.
I stopped, raised my head and looked classmates asked me what was happening.I just opened my mouth wide, looking up into the more and more classmates looked up asking what had happened on earth “Nothing! Just for fun!Haha..”I couldn’t help laughing Silent for a few secondsthey all laughed the students and teachers passing by laughed with us.
My act of happiness cheered others up, and cheering others up brought me a happier day.
