AIBU to be cross about this. My dd was partnered on her trip today with a challenging child from her class. I have just spent 2 hours comforting her as the other child made up stories to 'tell on her' and so she got into trouble for most of the day ( usually she is very quiet at school and has never been told off ) she said she was too shy to tell the adult they were with as it wasn't her teacher, or an adult she had met before.
She is 6 in y1 and this was her first school trip.
