I recently ran across a Wall Street Journal article claiming that good storytellers are happier people and have better relationships. The article is good as far as it goes, suggesting that bonding while storytelling is important, and that we do it early in the relationship but tend to fall off.
I’m going to go a step or two further. Sharing stories means creating a shared reality. If you and your partner build a consensus reality that strengthens the relationship. This is the reason why Jen and I share stories about ourself. In telling stories to others, we reinforce the emotions and associations of those stories.
