There were three friends who lived in one hotel room which was on floor 50! They went inside and saw the lift not working. So they had to take the stairs. One person suggested That I'll tell happy stories till we reach floor 20.Other said I'll tell frightening stories till floor 40.The third said I will tell sad stories till we reach floor 50. When they finally reached floor 50 the third person said I will tell u the saddest story we left the room key in the car.
