Stories.

A story doesn't have to be really long to get it's message across. It doesn't even need to be more than a couple of sentences. Here's an example -

"I woke up this morning to find a photo on my phone of myself sleeping.

I live alone."

It's short, it's sweet. It has context, you get the theme from it. It leaves you with chilling thoughts. It is a good story. But it's so short. Of course, it can be expanded upon. The two sentences could be extended to a much longer story, possibly even a book. But those sentences are enough. So little carries so much. That is the beauty of words.
