You are not a human being if you have never dug a hole deep enough to be able to hide in it.
Digging up holes is the single most liberating activity a homo sapiens can participate in - it has been with us for thousands of years and was widely used as a form of ritual, a therapy, meditation, a job, farming activity, religion, social gathering, food preparing, warehouse, a house, toilet, cage, trap, rain summoning, storage of frogs or as an agora!
Digging up a hole has always been with us, from the very begginings of civilisation as we know it. It is the most liberating activity one can participate in and honestly, you are not a man, a woman, a child nor an elder if you have never ever dug a hole in your whole life.
