I think silence is golden. Why do I think so? There are some points.
If you don’t keep silent, you will make your teachers and classmates unhappy. You will make them unable to concentrate in lessons.
Your friends may also hate you if you don’t keep silent and become too noisy, just like a loudmouth. No one likes to have a loudmouth friend.
Also, you may not be able to go into the school library because the school library is very quiet and it doesn’t let the students talk loudly. A loudmouth can’t go into the library to borrow or return books and no classmates will help you if you’re always chattering. Students can’t read their books quietly and you are breaking the library’s rules.
Silence is very important for everyone, and it is golden.
