You know those days when you've got the mean reds.... the blues are because you're getting fat or maybe it's been raining too long. You're sad, that's all. But the mean reds are horrible. You're afraid and you sweat like hell, but you don't know what you're afraid of. Except something bad is going to happen, only you don't know what it is.

Truman Capote, Breakfast at Tiffany's, 1958, spoken by the character Holly Golightly
