While I was at the post office last week

Last week when I was at the post office, the "black bagger" came in and took my lock for the gym out of my gym bag.  

I didn't notice it was missing until I was at the gym.  I changed into my gym sweats and I put my regular clothes into my gym bag, and I carried my gym bag with me to the Yoga class.  I was mindful of the irony that lugging my material possessions to a Yoga class might be at odds with the quest for inner tranquility.
