Explain the quote "It was coming. There was no stopping it now, January or not. One end of the cocoon dampened and gradually frayed in a furious battle. The whole cocoon twisted and slapped around in the bottom of the jar. The teacher fades, the classmates fade, I fade; I don’t remember anything but that thing’s struggle to be a moth or die trying. It emerged at last, a sodden crumple. It was a male; his long antennae were thickly plumed, as wide as his fat abdomen."
