Wind backing to southerly

My dad passed the eleven-plus.
His parents said, that's not for us.
He could have gone to Bradford Grammar.
Became an ironmonger, knew a hammer
From a hawk or handsaw.

I too passed the eleven-plus.
Went to grammar school. No fuss.
On the whole I'm glad I went.
Knew without telling what Hamlet meant—
Because of my dad.
