You should not speak in class while others are working since it may cause others to become distracted. If you speak while they are working, they may find it difficult to concentrate. Unless you are discussing the work in class, you will deviate from working as well. You should not speak in class while others are speaking to prevent distracting others and yourself.
It is very disrespectful a well as distracting. If someone is taking a test, they could get distracted and not finish the test. Which would result in a bad grade/ or redo. Especially if the teacher is talking, it is very rude and impolite to talk to each other.
