My wife and I are both studying Korean, and she is quite a bit more an advanced student. As part of my effort, I purchased 2.2 x 3.5-inch blank flash cards with binder ring to write words in Hangeul on one side and English on the other. I study vocabulary while walking, passing countless other people wearing white AirPods and listening to music. But today, I came upon kindred spirits, so to speak—likewise putting good use to their time walking.
Along Georgia Street, between Howard and Polk, in San Diego neighborhood University Heights, from behind I approached an elderly woman pushing a walker accompanied by another lady holding a smartphone from which came repeated English words. They studied a foreign language, too! The pair clearly were of Asian heritage, and I hoped Korean because wouldn’t that make a great story. But based on what little native tongue spoken between them, my guess is Japanese.
