It was wonderful to pick out the roads and soccer fields and parks and bigger homes. I barely dared to blink. And then we touched down and I felt the most extraordinary sense of calm. All of the tension that I have been carrying around with me lately melted into my pleather premium seat. I could breathe. I swear my back unclenched. I could have melted. It was divine.
