Yeah, same here. The thing was that we had a really small school district, so I was suddenly working alongside the folks who had been my teachers for most of my life.
My first school was really small, I started at three years old, it had one room, one teacher (no other staff), and the toilets were outside in the yard, it was in a small village called Birchover. At eight years old I moved to the 'big school' at Stanton-In-Peak - where there were two classrooms, indoor toilets, and even dinner ladies
At 11 years old, after passing my 11 plus, I went to Lady Manners Grammer School which at that time had 600 plus pupils, and teachers who wore gowns and mortar boards. It was like being in one of those old B&W school films . Manners went comprehensive the year I left, and built a big new extension, so has a lot more kids now.
BTW, if you check the school photos, I'm on the 1968 and 1970 ones! - and that's all the info I'm giving.
