Three days later I had an appointment across town, requiring significant walking and a bus. It was time. After downloading the app I quickly appreciated how many Pokémon Go users there are, as no variation of my name was available. I consulted a menu, avoiding the most obvious words. Not available: sunchoke, mackerel, tangerine, tagliatelle. Wow. I settled on bitterlettuces, then created my avatar. I was ready to go. I knew none of the rules.
