A Wigwam for a Goose's Bridle

Hearts are fickle things; love is
not a thing to be forced
like a lock. There is no jimmying,
no fancy trick with a credit card,
no skill to practise with thieves’ tools,
and thus it little profits
to say that you will make me
fall in love with you
if it’s the last thing you do. 
Locks are surprisingly simple,
if you have a key that fits. It would be
better to say not that you intend to force
the lock, but rather that you will strive
to become the key. I would have said
I will do what it takes
to become worthy of your love.
