Being a writer is like being a Hobbit. We’re sociable enough, only just, and especially if plied with ale (or, in some cases, weed). But we also know the value of being alone and keeping to ourselves. We are not wise in general, but we are thoughtful and given to rumination. And we all think we’re better than the others but are willing to condescend to being friendly with them anyway. After all, one never knows when one might need a helping hand.
