Saw this (H/T Twitter) , and had a memory:
The school was having an extension built.
The reinforced glazing (yes: it was that sort of area) [❉] had been installed, but there were still loose bricks about the site.
One evening a passing youth wanted to show his enthusiasm for state-financed education. He took a sand-faced fletton, as thus —
and chucked it at one of the windows.
Sadly, the youth must have missed the class on “angle of incidence” equals “angle of reflection”.
Our hero was straight-on to his target.
The window promptly pinged the fletton straight back.
It laid him out.
The real laugh was when the youth’s aggrieved mother tried to sue.
I can’t help wondering if that’s not a parable for the whole “Free School” business.
[❉] This is a well-constructed narrative. And here we see an example of “fore-shadowing”.
