An application for levitation

Busy times and haven't had much pk practice lately although my whole body itches for it.

Before reaching home today, I was stopped by an old lady. She said that her door had closed when she had gone outside for a moment. A girl brought a ladder (even though she lives on the first floor, it's about 2.5 to 3 meters to the railing), I climbed up the balcony and opened the door from the inside. She was in a hurry, as there was some kind of a soup boiling on the cooker. It was interesting that it was the same apartment I had been looking at each morning. I used to wonder who lived there before..

Now if something similar were to happen to someone living on the 3rd, 4th or even 9th floor, the only solutions would be either to levitate up there or call some kind of a special service with metal saws to cut through the door or with fire department ladders. The latter one would probably take so much time that there wouldn't be much left of the soup and / or kitchen (in the case of a gas cooker). That's a good enough reason learning levitation.
