As we were having lunch at our "perfect spot" this hiker was resting and gazing into the distance. I liked theway he rested and the way he was dressed. After some minutes of silence he yelled: "totori" [acorn]. We wondered what he meant by this, so CD asked him. Turned out he belongs to the local aread (Dongducheon) hiking club of that name. In Korean, a small but compactly strong and stubborn person is referred to as "acorn" - small but strong.
