I used to  go up to the garden area to the right of the  block as you exited where there was a pond with great crested newts,I was fascinated they were like small dinosaurs. You mentioned bullying  that you suffered, I went into the block one quiet day  late 60's and came across a really nasty scene of some one being bullied I was shocked and told the bully  to stop, he punched me but I think he stopped cant remember,he apologised to me next day,he should have apologised to his victim. This kid was someone that suffered quite a lot from bullying. However  I have a lot of good memories from my time there.
