Working at a convenience store, I encounter customers of all ages every day. One day, I was a bit flustered when my teacher showed up as a customer. I'm terrible in the mornings and often arrive late to class. That day was no exception—I overslept again and ended up late for this teacher's lecture. He had a gentle, serious demeanor, and since his classes were small, I wondered if he might already recognize me. Still, I greeted him with a smile. I was nervous as I processed his purchase, but then he surprised me by asking, "Want to come over to my place for a meal sometime?" My tension skyrocketed.
