There are many things in this world I do not know. I do not know how butterflies get out of their cocoons without damaging their wings. I do not know why anyone would boil vegetables when roasting them is much tastier. I do not know how to make olive oil, and I do not know why dogs bark before an earthquake, and I do not know why some people voluntarily choose to climb mountains where it is freezing and difficult to breathe, or live in the suburbs, where the coffee is watery and all of the houses look alike.
