A Ghost Story

A man and a woman happened to sit next to one another on a train
The women, took out a book and began reading
The train stopped at a half dozen stations but she never looked up once
The man watched her for a while, and then asked
«What are you reading?»
«It's a ghost story» she said, «It's very good, very spooky»
«Do you believe in ghosts?» he asked
«Yes I do» she replied, «There are ghosts everywhere»
«I don’t believe in them» he said «Just a lot of superstition, in all my years
I’ve never seen a ghost, not one»
«Haven't you?"The women said, and vanished
Do you believe in ghosts?
«There are ghosts everywhere»
