My grade 9 and grade 10 homeroom (currently grade 11) is so rude my friend takes MRT like metro in Taiwan and her homeroom teacher said that My friend can't leave before 17:00 but her train is at 16:50 and she said that if she doesn't follow she will report to the school office. How come she does that to my friend. Does she deserve to be a teacher? Does she needs to be fired or not she is not being a good teacher to my friend and does she needs to care about other people's business
