Both to create and to experience.
I'm a big fan of poetry, but sometimes when the mood is right and the pressure high enough I'll bang out a short story. One of my favorite things to read, though, is memoirs. There's nothing quite like a good memoir! It takes a lot of skill to be vulnerable and still tell a complete story. It's very reflective. Maybe one day I'll be brave enough to do that, but for now, I'll just enjoy my Mary Karr quietly.
I love stories the most but I dig a good poem too.
I prefer stories. Short stories are my personal favorite as they let me write what I want in a constrained format, which causes a interesting challenge. I prefer either type of story. Poetry is my second favorite. Finding the rhythm and rime is very fun once you get it right.
