I have a 10 year old with learning difficulties, very shy and very geeky. Iwas telling him off for something unrelated tonight when he said he was being moody because he had an argument with someone from secret swear club. I queried further. DS said they had a club (of 4. All very nice nerdier kids) and that they meet at a corner of the field and use s, f, c , sh words at each other. He really thinks this is the ultimate rebellion. DS is not rebellious in the slightest. His dinner ladies stop me in the street to say how nice and polite he is. I told DH thinking it was amusing. I laughed anyway. Now DH is saying he is going to have a big talk to him about why the language is completely inappropriate. Ds doesnt swear at home. I don't like hearing kids swearing myself but hes just being 10 isnt he?
