2 I can think of: The head teacher, the best a school could ask for (really) he retired in my 4th year, we then had 2 heads after but it was never the same. The school entered a downward spiral after that, plummeting down Scottish school league tables by about 70 places. The other was my physics teacher, possibly the best teacher I have ever had. Although I enjoyed Physics it could become a rather dry subject but he always was enthusiastic about it. He would even let me hang about with my friends when they were doing their advanced higher projects during the free periods.
