Children need to take responsibility for their own actions, lessons are not more than an hour, usually, so why can’t they wait until the end of lesson, mothers in this day and age are a nightmare to deal with, you can’t do right for doing wrong.
Where has the day and age of respect your adults gone, if you complained when I was at school, not only did you have your teachers to deal with but also your parents, bring back the good old days, that’s what I say.
