How people learn to lie

We agree that lying is a learned behavior. Lina lied because she learned it from the environment. I didn't put checks when she was lying, and probably let much of it slip. For her lying though I partially blame the Korean culture. People here would say many things, all sort of things, promise things easily, extremely easily, without actually thinking to follow through and to keep their words. I see that in Lina's Korean family, in so many people I worked with, in Lina's friends. To say the least, the majority of interactions I had with Koreans over years were dissaponting and basically instilled in me a chronic lack of trust and faith. At the back of my mind "do not trust a korean" is always present. Koreans do not mean to be udermining trust in themselves; they are product of their culture where faith and trust are just of different value and definition then in my culture or in the culture of my husband and other westerners I hang out with.
