When I walked into the small gym in our apartment building at 7:30 Monday morning, there was a yoga mat and foam roller lying in the open space where I planned to do my workout. Mary [not her real name] was running on the treadmill.
“Hi Mary. Is this yoga mat yours?” I asked.
“Yes,” she replied. “I’ll use it soon.”
So instead I began my workout in a small space squeezed between two posts.
Forty minutes later—after I finished my workout—Mary got off the treadmill and began to use the space she had been saving.
