A general store that gives advice turns magical one night. Accidentally, the time line switched which somehow makes the current present and the best present for the people who want to be advised.
Three derelicts are stuck inside an old store and cannot leave. They regroup to consider their options overnight. Then the mail arrives unexpectedly. It turns out that the building's owner doled out advice to anyone who wrote him and placed the replies for the seekers to collect. The three notice that this story is decades old.—aghaemi
