I believe mine is, or rather, was being able to walk up to my grandparents' farm and relax, whether it be in the trees or just laying there and watching the clouds. They no longer lived there because it was too bad to get back to in the winter, but at my old house, I could walk a back way and get there...after climbing through fences

Also, I could walk back gorgeous trails in the woods or ride my bike and it was relaxing enough. Now, where I am, I can no longer do that anymore. I have
no quiet place to myself anymore. That's why I consider that and when I used to have my own room a luxury.
