One of the first things I notice about another student when I meet them is their key ring. Lots of people have key rings, and usually they tell something about the person, whether it be their favorite sports team, their high school, an event they attended, or how they value fashion. If there are lots of keys, I may wonder if they live off campus, work part-time, or have a car. When people have lots of different keys, I enjoy hearing the story behind each one. A key ring is also incredibly functional, keeping everything organized in one place. When digital locks replace key rings in the near future,  I am going to miss seeing people’s unique key ring when I meet them!
