What a nice lift~~~

I came to school today white-faced. Why? I was taking the lift when a father entered with her daughter on the 9th storey. The lift went smoothly till between 7th and 8th floor when it suddenly vibrated so violently and came to a halt. It remained stationary for about a minute or so and crawled to 7th storey and opened its doors. I jumped out crazily and it was like wtf? It scared the hell outta my life!!!
