"Joy is not the absence of pain," says Ayn Rand. I say, pshaw. I'd been having a splitting headache all day, Reader. The kind that makes even smiling feel uncomfortable, the kind where you want to lie curled up in bed, your head wrapped in pillows, desperate for sleep or oblivion. Well, I finally fell asleep at eight, which is why I'm up now, at 3 am and annoyingly perky. My headache's gone, I have lots to do and I'm happy.
