Another Perfect Day: 08/22/08
"Another Perfect Day" reminds me most of Connie Willis's time travel books. As this short story by Steven Popkes is on the lighter side, I would say it's more like To Say Nothing of the Dog than Doomsday Book.
A man polishing his gun on the anniversary of his wife's death is visited by a man named Wilson Taylor who claims he' from the future and wants to stop his suicide. There's only one problem, he's not the right man, not in the right state and it's not the right year.
Usually what follows in these type of time travel stories is the person traveling from the future gets stuck for a while and the person in the past can't comprehend the notion of time travel. Not so in this story. What happens instead is more amusing than the typical plot.
