Two common observations about Korean people are their endurance and dynamism. Harsh weather, grueling negotiations and after-hours socializing are all taken in stride in a ‘work hard, play hard’ culture. The Korean sense of humor is readily apparent not only in daily interactions, but also in the nation's rich folk art. Favorite songs, often sung at the end of parties or dinners, have lilting sad melodies, pointing to the strong element of melancholy contained in the Korean character. Koreans tend to vent their feelings and emotions – be it exuberance or anger, delight or frustration.
