Wednesday's Brainteaser: Miss MaryDoll's Warmhearted, Welcoming, Witty, Wittering.

Good morning class, no mathematical calculations today, a brainteaser for a change. Variety is the spice of life!

Please, Please don't post the solution, PM me if you wish.

A lift is on the ground floor. There are four people in the lift, including me.
When the lift reaches the first floor, one person gets out and three people get in. The lift goes up to the second floor, two people get out six people get in.
It then goes up to the next floor up, no one gets out, but 12 people get in. Halfway up to the next floor the cable snaps, and the lift crashes to the floor. Everyone else dies in the lift. How did I survive?
