Our dd (13) is prone to various low-level misdemeanours in school: chatting in class, texting in class, not doing homework, arguing with teachers, "forgetting" a detention so gets a worse one etc. School give appropriate punishments (if anything they are on the trigger-happy side). Our instinct would be to leave it at that - as she said in the past when we piled extra things on top (eg confiscating phone for too many detentions) "Why are you punishing me for being punished?". The problem is that lately it doesn't seem to bother her that much getting these punishments. And we feel (perhaps wrongly) that this sort of behaviour raises moral issues - arrogance (silly rules don't apply to me), inconsiderateness (I can disrupt the class if I feel like it) and harm to herself (school is for messing around in not learning), and that it's our parental role to send a message that this sort of behaviour is not OK. Should we do something, and if so, what?
