we get formed in fire, and then just mind our own business being rocks, not bothering anyone, until people decide that they need two showers a day and the car washed on Sundays, so along comes a digger to lay a new water main and we get picked up, crushed, and dumped out of the way, to be sneered at by dogs. Tain't fair.
