Postbox

She stuck the stamp in the upper righthand corner of the envelope and slid the letter into the slot of the big red pillar box.
Something grabbed her hand.
"What the?"
Her arm was pulled inside all the way up to the shoulder.
The pillarbox spilt in half and she was pulled inside.
It sealed behind her.
She was dropped in a huge pile of letters as the postman with whisky on his breath who lurked in the shadows laughed maniacally.
