I actually mentioned this on another thread before but its worth repeating....or is it..?
When my husband was young (13 or 14) he and a few friend were hanging out in front of the school at lunch, when they noticed a very large rock on the ground before them. They contemplated it for awhile, trying to decide where such a large rock, so out of place, could have come from and decided, after some deliberation, that perhaps it had fallen from the sky. It seemed to be such a dilemma to all concerned, that my husband decided if it had indeed fallen from the sky, they should send it back from whence it came, so that they could get on with more important things.
My husband picked up the rock and heaved it up and back over his head and instead of the thump that they had expected, as it landed on the flat roof of the school, a loud crash of glass was the result, for the rock had plummeted through a skylight. They carefully removed themselves from the vicinity doing their best to look nonchalant.
It was not until thirty years later, when he was working with an old school mate that he found what had truly happened to the rock. The friend recounted how, while he was working on a drafting project at lunch one day, a very large rock had came hurtling through the skylight and had landed on the desk in front of the dreaded Mr. Bagshaw, the bane of their young existence and that the old boy was shook up for weeks afterward. My husband responded, "Yeah? weird how things fall from the sky sometimes."
