How can a boy without talent be embarrassed to perform in front of his classmates?

If you really can't get away, pretend to be calm and say with confidence, "OK, I'll sing you a song." At this time, everyone is probably curious, "When does this fool sing well?" "I haven't sung a single song since I've known him for so long …" Then, I cleared my throat and said, "This is my best song, which represents my best memory …" It is estimated that friends who are familiar with you will be even more surprised at this time. "This buddy is still a man with a story." Finally, I will tell you: "this is an English song, but I haven't sung it for many years, and it may not sound good, but I hope everyone can give me a beat when I sing, ok?" At this time, I think everyone is expecting your performance, and the scene is very quiet. The stage belongs to you. Just shake your body, take two steps, and then: "A, B, C, D, E, F, G …" until the scene is out of control.
