leave before the lights come on

" and how can you wake up,
with someone you don't love?
and not feel slightly fazed by it,

and they woke up together not quite realising how,
awkwardly stretching and yawning,
it's always hard in the morning,

and I suppose that's the price you pay,
well oh it isn't what it was,
she's thinking he looks different today,
and now there's nothing left to guess now,

quick, let's leave, before the lights come on,
'cos then you don't have to see,
'cos then you don't have to see,
what you've done... " - The Arctic Monkeys.
