Korean grammar

9/9

When I entered my apartment enterance, a manager who manages my apartment yelled.
He asked me that I heard a fastfood restaurant like a Subway. First time. I didn't listen clearly. So, I request to say again. He said again, but It is too difficult to listen and understand. So, I gave up to hear that name. So, I pretended to listen and answered "I never heard that."
He yelled again. "Just 5dollars!! YEAH!!"

I met Scott at luch break. I talked one my Korean friend's mistake. He called himself 오빠(Oppa) infront of me. In Korean, Elder man be called 오빠 by younger woman. So, I said "He treated me like a girl." He laughed. Then, He asked me about Korean grammar. "What does 가(ga) mean?" "Ah.. It's difficult to explain. Because, English doesn't have this. In English, There is no words after subject. For example, I am a boy. I play baseball. I is just I. Right? But As you know, Korean grammar process is subject, object and verb. And, after subject word is changed because of verb and object. I is 나(na) in Korean But, even if subject is I, because of verb and object, we speak different, like 나는(na nun) and 내가(nae ga)." I felt he doesn't understand clearly, but he said that he understood. "That's interesting. This is a reason why I am studying my major." he said.
