See Tim Lenton's poem Forgiven.
When you walked out across the burning bridge
and threw your keys into the sand
I tried to strip you from my mind
like wallpaper.
Parts of you came off easily,
without a struggle, as if
you were just hanging there prettily,
never really attached.
But other parts stuck fast,
even though I diluted you
with liquid
and scraped hard into the night.
Months later, after much rubbing,
the wall looks smooth.
But if I run my fingers over it
I can still feel
your goosebumps on
its thin, thin skin.
