There was a merciless gnawing in my chest, a queer silent labor was going on in there. I pictured a score of nice teeny-weeny animals that cocked their heads to one side and gnawed a bit, then cocked their heads to the other side and gnawed a bit, lay perfectly still for a moment, then began anew and bored their way in without a sound and without haste, leaving empty stretches behind them wherever they went.
