The most difficult experience I have ever had was acting in public without practice. There was a musical play in my class at school. We practiced every day and tried to do our best to present the personality of each role. The day we had to perform, everyone came. That morning, our director told me that someone needed time to change her clothes, so I needed to think of something to say before our dialogue. But I could not think of anything to say and I thought that it was very strange to say things by myself. When performing, I had no idea what I said for such a long time. Maybe I just read something for the latest newspaper and added some funny things in my lines. After the performance, many people said that the role I played was very funny. But they did not know that I did a improvisational performance at that time.
