Walls and Security- Eisenburg

I understand the idea of walls protecting us. However, most of the time I would prefer openness. Even being outside of walls can feel as though you are trapped. Trees and mountains can provide a sense of security while outdoors. Given the option, nature providing me security is preferred to walls. While camping, a tent while sleeping is the only safety I want. This only serves as a prevention of getting soaked from rain and being eaten alive from bugs. While I'm not sleeping I prefer to stay out in the open and experience nature.
