I now have the perfect writer's lair! A few weeks ago, my dad set up the spare, slower computer in the basement and almost instantly I discovered the atmosphere I've been searching for. It's a great place. It's a lair, a cave, a subterranean creative depository, it's perfect. It's dark, located adjacent to the furnace so it's warm, and full of interesting sounds such as the furnace turning on and off, the sump pump doing it's watery thang, and the beer refrigerator's steady hum. It's almost like a womb!
I even found a comfy terrycloth bathrobe in the laundry room downstairs, so my writer's lifestyle is nearly complete.
Check out Neil Gaiman. He's definitely a kindred spirit. Check out his lair!
