Sir was Not Suited

Over 99.9999 per cent of what
I was ever taught has slipped
from me/ I have been re-filling
gaps since my school classes
[writing groups do NOT count]

State schools did us all in with
their pettiness of endless lines
[we were paraded as if troops –
taught to never try to advance
by war-served suited teachers]

Groovy bearded Sirs [caught in
London’s petri dish of suburbs
& sick of war in Vietnam] took
no prisoners – they were equal
in their rigidity – we all become

members of an old guard once
our guard falls off – they taught
us enough – I still keep to rules
but cannot recall trigonometry/
A shock we don’t like teachers?
