It’s not that I’m surprised at being the youngest person in my water aerobics class. I was taken aback, however, when I realized on my first day there, that had she come with me, my mother would have been the youngest one there. The fact that I had somehow signed up for an exercise class that was clearly for elderly women was so absurd to me that during the first twenty minutes of that initial session, it was all I could do to resist bursting into giggles. I bit the inside of my lips. I closed my eyes and did yoga breathing. And I made it. I did not collapse into laughter. I honestly wasn’t sure if I could go back a second time though. What were the odds that I could keep it together twice?
