Hello there! My name is Garry and i'll help you out!
Many students that do not bring books to class and disturb others tend to be lazy and irresponsible. They are often too focused on other stuff at home such as playing with their friends that they forget to do their work. They can be disturbing in class and the best way to solve this particular issue is to just ignore them. If they continue to do this, then u can let your teacher know. Then this problem can be resolved quickly.
Thanks! I hope it helps!
