I had a theory that all years ending in a 7 were bad years. Can't remember what was so bad about 1977, but 1987 was the last year of the hell known as Secondary School life. OK, I stayed on an extra 2 years for 6th form at the same school. I really should have gone somewhere else, but was probably too scared to tell my parents what a miserable, depressing, soulless and lonely period the previous 2 years had been.
Anyway, got good results at O-levels, and 6th Form was a lot better, but discovered 2 years later that a clean break might have been better for my sanity.
