Do you like Short Stories? :)

They really help getting me to sleep, and they've saved me quite a few times when I needed some space from my own head.

Two of my favorites are La Horla by Guy de Maupassant and The Machine Stops by E.M Forster .

What are some of your favorite short stories? Are there any you've read recently that left their mark on you? 

Long enough for a glimpse, small enough so the mind can wander. :)
