Air-conditioning: A new invention so you don't have to sleep with your neighbors in the grass at the park across the street when it gets hot.
Something inside me greatly desires a life like that. Where we aren't afraid of the people around us. Where it would be totally acceptable to throw a blanket on the ground at the park with my neighbors and enjoy some cool night air while we all get some rest. Today, I think we'd all get arrested, or ticketed.
While it sounds miserable to be without A/C, it can be argued that we are even more miserable now because we have it.
