Sometimes all we want is a nice quiet space to practice yoga. We come to class and set down our mat in the perfect spot—with plenty of space in every direction. We enter a relaxing posture as we wait for class to begin. Then, someone sets down her mat to our right, closer than we might like. Then, someone else sets their mat down to the left, closing in. Soon, the entire room fills up with mats squeezing closer and closer together until it seems like no one else could possibly fit—until someone else does.
