As a boy, I was extremely wary of my woodwork master, Mr Ruffett, who was noted for bringing down a steel ruler on the knuckles of inattentive children.
I was particularly apprehensive about igniting his wrath because I couldn't execute even the simplest woodworking exercise, such as turning raw wood into pointless household ornaments, like a mantelpiece pipe stand.
This exercise seemed even more pointless than usual, as nobody in my household smoked a pipe, or was likely to in the immediate future.
Because of my ineptitude, I never moved on and each term I faced the same construction exercise.
In my last year at that school, bored with constructing pipe stands, when Ruffett's back was turned I instead created a make-believe wristwatch cut from a thin balsawood sheet and taped it to my wrist.
