It's not an entire story but a short statement by a non-believer in relation to the statement of a boy (main character of the book "Pigeon English") who, in contrast, does have a strong faith and makes this clear in the course of the story. In the book (not included here), he makes frequent allusions to the views and lifestyles of non-believers. The following text revolves around one of these statements:
'People who don't follow God are called non-believers. They're lost in the dark
and they can't feel anything, they're just empty inside like a robot with the wires
taken out. When something good happens they don't even feel it and they don't
even know when they do something bad. Asweh, it must be very boring. A
vampire is like that. A vampire has no soul or blood, that's why he's sad all the
time.' (Pigeon English, 2011)
