1. My body is too tired to nap. My body is the tired that fidgets along the edge of sleep.
2. Because my body is so tired, I can't get anything done around the house, physically. My muscles give out. My legs, they drag.
I know that, if I napped, my body would be refreshed enough to get stuff done.
But my body refuses to settle down and nap.
This is, how you say, frustrating.
Doubly so because I'm too tired to concentrate on anything. So reading and writing are not options.
Stupid body. Hulk smash.
EDIT: BTW? This has been this way all week.
