We had to know all of that [flora and fauna] by heart, what it looks like, and so on. Labor force, hoes, and human labor, meaning female labor. But pure ecology, which we still adhere to today. Meaning the garden, the vegetable garden, the orchard, and so on. Nothing is sprayed. We don’t have large yields there, but we have clean and healthy food. … So I try to show my grandchildren the most important things in family life, which are also related to ecology, to healthy production; I teach them which wood is which. … We have a story that oaks are kings, that linden trees are princesses, and so on. I wrap it up in little bows.
