Sounds like the sister was bullied for being different and suspended for something with no real evidence.
so she says, but the school can't release anymore details because of some form the parents wont sign. if she was being bullied and suspended with no real evidence surely that would show up in the schools report so why are the parents not allowing the school to release any more info?
maybe because she wasn't being bullied and maybe they did have evidence she made such a claim
