Write a short story, drawing on one or more of the following problems:

There must be a letter delivered in time.
A telephone must be answered if a life is to be saved.
A key must be inserted into a padlock.
Shelter must be built.
An object must be found.

Start anywhere you wish ... at a particular location, with the thoughts of a character, by describing what it is like to touch an object. Then see where your beginning takes you.
