Glazed over eyes. Slumped shoulders. A suddenly weighty cranium that keeps dipping toward the keyboard. Even heavier eyelids. Eyes that constantly sneak peeks at the clock, which seems to tick ever more slowly (the more you look). Work piling up without regard for your inability to acknowledge its presence.
My apologies for the string of sentence fragments, but my mind simply isn’t working quite right. I’m in the midst of ruminating on the dreaded mid afternoon slump. For my money, it’s the worst feeling in the world.
