First - DS2 got a letter home saying he ahs nto returned a library book that he borrowed on 14th jan. They are allowed 2 books each. he currently has Willy Wonka in his school drwaer. The other one was about Monsters. It's not at home, we have looked,a nd he doesn't often bring his books home. I have looked in his drawer at school, and the teacher ahd a quick look in the other drawers for me. So now the school are saying they want £5 to buy anew one. They did this once before and it turns out the book had been returned. AIBU in not wanting to pay for a book that we don't have?
