What if the school doesn't get to know/believe what's what?
The niece and nephew involved come from a prominent, influential 'founding' family in our town. The school's interest would be in siding with a version that indicates they might be at risk from me and my kids. Heck, we can't even pay the school fees any more....
My Daughter recently missed out on being nominated as head girl for her House at school. She was the prime candidate (in terms of length of time at the school, sports and musical achievement, community service, etc). But she was passed over. Everyone thought it was a foregone conclusion that she would get the position. When it didn't happen she was devastated. I'm now beginning to put 2 and 2 together.
To answer your question, I told the kids I'd go and speak to their schools. D17 said she would also speak to her HOH to ask what her father had been saying about things. She wants to set the record straight, as it were.
