While not everyone will agree with old saying that your schooldays are the best days of your life, there's no doubt they shaped our lives.
For some of us, it's been a long time since we last sampled the delights of the school canteen, or took our final exams. But many of us will still have friends they met at school, or remember a particular teacher that made a great impression on us.
We probably remember our school corridors teeming with noise and energy. But as time goes by, the classrooms of some of our old schools, holding so many memories, fall silent for good.
