The difference between my students and other students

Every time I should go to work by train. Today when I went to work, I got on the train. I saw a lot of students in the railway carriage. They are cram school students. I thought they have outside activities, so they had to take train. There was a thing makes me very surprise that is they all spoke English, and they didn’t feel embarrassing and didn’t afraid of said in wrong way. I thought they are so brave that they speak out loud.
How about my students? My students are afraid of speak loud because they afraid of speak wrong. That is a big different between my students and other students. I hope they learn English and they can use it in daily life. Even though they will make some mistakes, but they can learn a lot from these mistakes. Therefore, they can learn English well.
