My mistake

I took Practical English Test (Eiken) last week. It was interview test. I was so nervous. However, the examiner was so kind. So I could do my best. When the test finished and I tried to leave the room, I said "Thank you very much! See you!". Then the examiner laughed. I was satisfied with my work. After that, my parents picked me up and I talked about the test. Then, my mother said "You are so stupid! "See you mean" is hope to meet you again, right?" So I checked the mean. My mother was right!
