Lesson learned: if you try to make a quick run to Walgreens and deliberately leave all your chalk art tools behind the city of Memphis feels about temporary un-commissioned installations, every single piece of sidewalk you walk over will wink up seductively until one finally smiles outright and you remember that you have four pieces of chalk in an old cigarette case in your pocket and five minutes to spare so what the hell.
Title: "Picture Day"
Time: 7 minutes
Security guard: initially concerned, then chuckling too much to report me to the cops.
