It’ll be a reasonable hour to go to bed. And I’ll be tired—not exhausted, or bored, or drowsy, but legitimately tired—and my eyes will be heavy and I’ll be in a warm, comfortable place.
But I’ll be reading, so I’ll tell myself that I want to get through one more chapter. So I’ll stick it through and read on.
And then after I finish reading, I’ll find that I won’t be tired anymore.
Whatever. I’ll sleep when I’m dead.
