How to make everybody happy

  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.
