"It irritates me when other people laugh and still look attractive, but when I laugh, I look like a demon showing teeth."
It happens in the real world. When we see others doing something, it fascinates us. But when we try that, we feel it is not our cup of tea. Some people are blessed with great talent. Whatever they do, suits them and makes them a point of attraction. But when you try, it becomes laughing stock for everybody. So practice before you go.
