My primary school was also one that banned the giving of Christmas cards one year, we also had a new head teacher in our last year, I wasnt a mushy kid that cried and gave milk tray wrapped in cellophane went teachers left, infact I would go as far as saying it grossed me out, but other kids cried when the last head left. This new one didnt want any decor of christmas round the school, she said so "not to upset other religions", we had a winter fete instead of a Christmas one and so on - this was in the early-mid 90s, so very premature for this type of behaviour and it went down like a lead balloon. She was just a right Scrooge, a miserable, stone faced, old trollop. She wore purple lipstick and had jowls that wobbled like a Bulldogs. My siblings were in lower years and apparently christmas was celebrated again but alot less "locomotion".
