The paedophiliac?

I sat on a park bench beside another old man
we saw a beautiful 17 years old girl walking past
and I said: we can’t get any of them.
The old my smile and said she is my granddaughter
and I sleep with her every night
My God! Another ****, Got out of my seat and hasted away
in my case slowly.
The old man died, they tend to do so. At the funeral
his granddaughter said to me never liked him much
but he made me do it.
She looked at me with eyes as glacial as the Arctic before it began
to thaw and asked: will you be my Valentine?
