I think of a story "teller" as a charismatic person verbally relating a tall tale with colorful words and gestures to a group of eager ears around a camp fire. I'm definitely not that. That's a gift I surely do not possess.
When pressed to tell live stories to an audience, I shrivel, and stutter, and rub my nose nervously. I look like a big geek. I flounder for the right words. Everybody loses interest before I'm anywhere near making the point. I'm a horrible, horrible storyteller.
But I love stories, and I have stories, which is why I've become a writer. I can sit back in my fortress of solitude and carefully carve out a good story, even if it takes years.
My father, and my brother on the other hand, are great tellers. At family gatherings, we could sit and listen to them for hours, but neither of them has ever bothered to write, and if you ask them, they'll tell you that they can't.
