When I was at school, of course we smoked and drank, but it was done in private; in our studies, away from the prying eyes of anyone senior. To have been caught would have meant a whacking.
My study was rarely without a packet of fancy Sobranie cigs, as well as a bottle of very cheap and nasty British Sherry called 'English Rose'. We thought ourselves very sophisticated when we offered visitors a glass of this foul Sherry. Our only saving grace was that it was served in nice pukka Sherry glasses.
I have just come across this hazy (smokey?) photo of boys at my old school openly drinking and smoking at someone's school birthday bash, and I must say that I find it rather disappointing.
Making such activities 'legal' (as I presume it now must be for V1th formers) takes away all the fun and subterfuge of hiding a sherry bottle in an emptied Fire Extinguisher, or burning toast to mask the smell of tobacco (as we did).
Do today's boys no longer learn the art of deceit and circumvention? It's a disgrace.
