I wasn't a hard kid and I played a musical instrument, so I didn't qualify for the top floor of the bus. However from my vantage point on the bottom deck of the bus I was afforded a cracking view of one of the top floor windows, having been kicked out at some speed, narrowly missing the teacher on bus duty.
I learned two amazing facts that day:

1. You can drop a bus window from the full height of a double decker bus onto concrete and still have it not break.
2. You can get away with such a wanton act of destruction under the weak guise of "trying to kill a wasp".

If I'd been a bit harder I would have been able to give you the top-floor-of-the-bus-point-of-view of that story which I'm sure is far more sexy and dangerous. As it is, I can instead play the violin to an extremely low standard.
