Something familiar can have facets you never knew existed. People can move a piece of furniture, and find doors to hidden rooms in a house they had lived in for twenty years.
This also applies to your garden. Your lawn is made of as many different plants as people in a small town. Add in the insects, and you reach a city. Add the microbes, and the number dwarfs the world’s population before you reach the fence. Pull up the plants, and the amount of life is almost infinite.
So far, so uncontroversial. But the odd plant will resist your tugging. A daisy will give the resistance of a tree stump. Keep tugging. Remove a root that strong, and you will create a hole big enough to jump in.
Even if you do jump in, you may still end up in nothing more than a pile of dirt. But there is a possibility you will enter the Spaghetti Sea.
The Spaghetti Sea is the result of generations pulling up these giant roots. You can walk through the created tunnels, and the cities, forests and mountains will be above your head. Some are so old that empty tin cans from the Second World War litter the dirt. People have wandered the musty tunnels for twenty years. Visit China if you want.
There is no shame in fear. In deciding this place is not for you. Nobody has to walk to the centre of the Amazon Delta. But never forget the wonder. The ocean under land. Remember that wherever you are, whatever you are doing, underneath some are walking the tunnels of the Spaghetti Sea.
