I can hear you digging in the snack cabinet again, and it’s got me thinking about a piece in Natural Geographic about caterpillars in which the author calls them “cylindrical eating machines.” Caterpillars grow extraordinarily fast due to constant feeding, I learn, molting several times before the pupal stage. That makes me think of you, since your appetite seems to refresh on the hour.
At some point, a specific hormone surges prompting the caterpillar to spin a pad of silk. In the pad of silk, the caterpillar embeds its cremaster (fancy name for “hook”), then hangs itself like a Christmas ornament for the mystical process of metamorphosis. In the chrysalis stage, the caterpillar liquefies into what one scientist refers to as a “chunky stew” while specialized cells with the coolest name - imaginal discs - dictate the remodel. There are imaginal discs for wings, legs, and antennae. Eventually, the cylindrical eating machine emerges as a winged butterfly equipped to sip sugar from flowers with a proboscis that looks like a straw.
You’ve molted at least three times this year, Toots, upping an entire shoe size in less than three months. I suspect you’re approaching the pupal stage. Your body grows beyond itself, sometimes overnight. Once hormones dictate it’s time to dissolve into goo, I think you’ll find imaginal discs for eyebrows that connect in the center, as well as an aversion to working in groups. Let’s hope you get your sense of direction from your dad, since I still get lost in my home town.
But how crazy, these changes! Never again will you undergo such rapid growth in such a short stretch of time! I feel for you, burgeoning child, your brain flooded with hormones that whisper wicked things in your ear, swearing everything I do is intolerable. The furious amygdala of puberty leaves you vexed when I laugh off your annoyance, a helpful tactic that allows me to dodge the laser beams you aim on the hour. I refuse to stop having fun because you loathe me, sweet girl. So, go ahead and attach your silk to the red maple of my heart and liquify while I keep the mildest of weather, and one of these days you’ll forgive me for being merry.
Just this morning, I reigned in laughter when you became angry in response to whether you’d like pancakes, and when you returned to the kitchen table to devour them after sulking in your bedroom, the pat of butter had just begun to melt.
