This is the way I maked all the students happy。
One Monday。 Tom and I went to Simon's office。 Suddenly， I was slipping and fell， because there was some water on the floor。
When I stood up I thought: If I took the mop and dry the floor， nobody would slip and fall。 then， I took the mop and dry the floor。 Tom also helped me drying the floor。
So I maked all the students happy。
