Much of the interesting conflict and suspense in fiction comes when one character can't tell what another character thinks... so let's throw that all out the window and write stories about telepathy.

Other than that, go hog wild. Write about mind-readers. Write about identical twins who can mind-talk with each other. What would caveman telepathy look like before language was invented -- or what's the Cyberlink like in the year 2525?

You get 1200 words to work with. If you ask for a flash, I will give you ~something~ to work into your story, plus an extra 400 words.
