picked up DS 9 last night and his friends from cubs - talk turns to swearing and a particular child at school who is using 4 letter words. One of them tells me this kid told a group of them to F*k off in the playground at lunch, then DS says the same kid said to him last week, and I quote 'you are a piece of sht'. Really not happy about this (understatement) but what do other people do? its parents evening this week but don't want to waste 10 mins talking about someone elses potty mouthed child! what would you do - catch teacher at home time or ring school to speak to head? how do other people handle this sort of thing?? advice please! This boy has got previous on this sort of thing but this really bothered me.
