This flighty thing called love... The O.E.D.
Could not attempt a formal definition
Or tell you why exactly it can be
Too often but emotional malnutrition
Or sublimated lust, or strong approval,
And sad responsibility mistaken,
To try and weary – after its removal
It needs must leave you both fed up and shaken.
Still, just a whiff of scent, a timid smile
Or the suggestion of some tanned young flesh
May well convince you you're in love once more
To wonder, after just a little while
What masochism made you hurt afresh -
It never leaves you wiser than before.
