something I felt regretful something I felt regretful I really felt regretful of being so shy to say . I met a USA couple in LiJiang, they were friendly and said 你好 to me,I talked to them for only a short time, just because I didn't understand what they said to me well, and I pretend to understand it. finally, I only can smile to them with no words. Everytime I think of it, I just ask myself: if I told them that I didn't get what they said well, and asked them to reply it, will the result be different? But all is gone, the only thing I can do now is being brave and do what that I will never regret. thank you for your correction.
