when I'm outside the classroom with my friends when the lesson starts. we went to the cafeteria to eat and drink. after finishing straight back to the classroom, the teacher turns unexpectedly we've got class and she was teaching. Our confused what to do? we finally get in with not pretend to know. teachers do not receive because we came in late. we also are not allowed to go in and we're in trouble because the teacher is very cruel. in the end we also regret our actions and will not repeat it again.
