My 15 yr old DD has just been excluded from school for 2 days, for being caught using her mobile phone in school to take photos, then posted on Twitter. Several girls in same boat. Exclusion seemed extreme, but it is the 2nd time it's happened. Spent much time discussing reasons she did it ('everyone else does it'), trying to support both her and the school's hard line view on this. Have re-inclusion interview tomorrow so attempted to discuss with her what is an appropriate way to show remorse etc. However she became completely grumpy, wouldn't speak, walked out of the house (came back in 15/20 mins) went back to her room, cried, still refusing to speak. Have explained we are attempting to help her back in to school without creating further problems. It's so frustrating she won't take the slightest bit of advice/support. Where have we gone wrong??
