Though I've meant to for a decade I have yet to attend a yoga class. They offer it at my gym at no additional charge so there are always lots of people walking around in yoga clothes toting yoga mats, but I can tell that whatever they're doing in class isn't working for the ones I shared the elevator with the other day. Our elevator creeps up and down, from first floor reception to the 9th floor gym, and the two yoga women I shared the ride with began yelling at each other over the slowness of the elevator. "Breathe," I imagined myself saying to them in a slow, measured voice. Then I imagined them beating me up and held my tongue.
