not born in--mum got religion when i was 9...but your post is ME!
Went to all boys grammar school in Birmingham ( UK) aged 11. Kept out of assemblies--along with catholics, jews and a couple of hindu.
I went completely off the spectrum--smoking in the bogs, truant, fighting, no homework. Tell me about the caning, the flying blackboard dusters--punched by teachers.
O level in skyving...managed to get out of it all when i was 15 and got a job.
Happy days
