When I was in year 11 (aged 16) at school, we had a brilliant English teacher who had a massive cupboard in the back of her classroom full of old books that were never used. We always joked with her that when we left at the end of year 11, she would give us all a book to save her having to clear them out. When it came to the end of year 11 before we left, she had in fact picked out a book for each of us personally, wrote a message for us each in the book and gave them out. I got 'Tom's Midnight Garden' by Philippa Pearce so I treasure that book from such a brilliant teacher
