It's All Relative

Relatively speaking, this could be considered small. It's easy to lose a pound coin, for it to drop through that hole in your pocket and be picked up by someone else who will no doubt lead it to a far more exotic and fulfilling life.
Similarly that marble whose cunning knows no bounds when it comes to escaping the nightly clean may seem insignificant until you tread on it first thing in the morning in bare feet.

Now picture a stone with the diameter of that pound coin and place it in a small coin purse, the sort your Grandma may have kept her small change and peppermints in.

Therein may be the hiccup in the glorious belch of progress. I have somehow managed, despite years of careful abstinence (honestly, why else would I need a health overhaul?), to develop a gallstone that is a third of the size of the entire gallbladder - and that's just the largest one. But for now at least I am spared an operation, the surgeon will see me again in 6 months for another review.

For the record, I really believe that in order to give a man the chance to feel something akin to child birth he should get a whacking great stone in his gallbladder and fall victim to the pure evil that is a 12hour gallbladder attack. 

As a veteran of both I can testify to the mindbending hell that makes that entonox bearing paramedic a God of Salvation.

I am not sure if it's my imagination but the level of the canal seems a little lower than it should be. And the sound of Goblins tunneling has gone away. Maybe they learned how to swim, but probably not.
