I worked my tailfeathers off and the steam totally left me at 3 pm and had 2 more hours to go at work. And that was after having the sleep study last night with very little sleep, LOL.
Actually, my feathers didn't fall off, but my brain had to go on overdrive for the tasks at hand and when I got the biggest one done, my brain went 'whoooosh', like the air out of a balloon.
