Буллинг в школе

At my kids old school my son was being bullied so i went to the school to talk to the principal and she was extremely rude so i went down to the school board and made a report and the principal told me i dont think our school is fit for you all i said you know what your right and we left that school i remember thinking they must deal with parents who dont love their kids because why would that upset her so now at this new school i got my kids approved to go there its a A+ school so i did all i had to do to make sure my babies got in there the schools by where i live have a 1 rating so anyways the bus drive is about 20mins i asked the teachers if it was ok to email them to see if my children got to school safe all of them said yes but yesterday one of the teachers complained and the front office called me! I only send one email i dont write all day but it bothered her..... Im like do the other kids parents not care for them like why would that upset you? Whatever the other two teachers are cool with it.
