Strange and mysterious creatures who work alone in darkened spaces.
When encouraged by kind words, a writer can be openly gregarious to the point of excess. They are mostly incredibly witty, and underneath the layers of unwashed, unkempt creativity, are usually beautiful souls to spend time with.
Alternatively, they are also known as people who enjoy only their own company, deliberately keep antisocial hours to avoid contact with others, and delight in torturing themselves in order that they might finally have something to write about. Writers, in an odd shift of physical precedent, rarely ever get what's coming to them.
