Sophie slept in many places during her research of houselessness*. This is one of the many nests she found, when she voluntarily lived without a house.
*Sophie: I use the term "houseless" rather than "homeless" when referring to my own experience. As I was choosing this lifestyle, I was not "homeless", and my experience is entirely different to those in this position involuntarily. My decision was born out of a desire to feel at home wherever I am.
