Monday, 8:15 AM

I have been plunged into the abyss. Just moments ago, I was resting peacefully in the controlled, refrigerated climate of the corner store, my silver foil gleaming under the fluorescent lights, a proud sixty-percent cacao masterpiece. Now, I am entombed in the dark, polyester depths of a middle school backpack. The transition was jarring. A hand—sticky with what I suspect was orange juice—snatched me from the shelf and shoved me into this cavernous void. My current neighbors include a leaking blue gel pen, a crumpled permission slip for a field trip to a landfill, and a massive, leather-bound Pre-Algebra textbook that looms over me like a tectonic plate. The air is stale, smelling faintly of sour laundry and pencil shavings. I must maintain my structural integrity. I am a premium confection; I will not crumble.

Monday, 3:30 PM

Disaster has struck. It turns out that a middle school locker is essentially a thermal conductor. For the last six hours, this backpack has been hanging in a metal box adjacent to the boiler room. The ambient temperature has risen significantly. I can feel my molecules beginning to vibrate with an uncharacteristic franticness. My snap—the very thing that defines a high-quality chocolate bar—is under threat. I am softening. The Pre-Algebra book shifted during the walk to the bus, and I am now slightly bowed. If I lose my shape now, who am I? Just a sugary slurry trapped in a foil suit. I must focus on the cool thoughts: alpine peaks, winter frosts, the icy breath of a freezer door left ajar.

Tuesday, 10:45 AM

I survived the night, but today brings new horrors. The backpack is currently sitting on a patch of floor directly in the path of a sunbeam. Through the thin nylon fabric, I can feel the solar radiation doing its worst. The blue gel pen has officially given up; a glob of cerulean ink is slowly migrating toward my lower left corner. More pressingly, I have reached a state of semi-viscosity. I am no longer a solid; I am a highly concentrated liquid masquerading as a rectangle. I felt the student’s hand reach in earlier. My heart—or the air pocket where my heart would be—raced. Was this the end? Was I to be consumed in this compromised state? No. He grabbed a bag of salt-and-vinegar chips instead. The insult of being passed over for a potato-based snack is stinging, but the relief is greater. I need time to recalibrate.

Wednesday, 12:15 PM

The humidity is the real enemy. We are in the cafeteria now, and the steam from the ‘Taco Wednesday’ trays is permeating the backpack’s fibers. I am experiencing what we in the industry call ‘bloom.’ The cocoa butter is rising to the surface in a desperate attempt to escape the heat, leaving white, dusty streaks across my once-pristine complexion. I look like a ghost of my former self. I am being pressed harder against the Pre-Algebra book. I have taken on its texture; I can feel the indentations of the embossed ‘Chapter 4: Linear Equations’ on my back. I am becoming a literal representation of mathematics. It is a humiliating transformation for a bar of my lineage.

Thursday, 2:00 PM

A miracle occurred, followed immediately by a catastrophe. The backpack was moved to the air-conditioned library. For two glorious hours, I felt the fever break. My molecules began to settle. I started to firm up, hoping against hope that I might return to a state of brittle perfection. But the cooling was uneven. I am now ‘set’ in a bizarre, twisted shape, resembling a discarded piece of driftwood rather than a culinary delight. To make matters worse, a half-eaten apple was tossed into the main compartment. The moisture levels are off the charts. I am surrounded by the scent of oxidizing fruit and the slow, rhythmic thumping of the student’s footsteps as he runs to catch the bus. Each thump is a physical assault on my fragile, warped body.

Friday, 4:00 PM

The week is ending, and I am a changed substance. I am no longer the bar that left the corner store on Monday morning. I have been melted, compressed, bloomed, and chilled into a gnarled lump of cocoa solids and despair. The zipper of the backpack finally hissed open in the quiet of the student’s bedroom. Light flooded in—actual, natural light. The hand reached in again, moving past the leaked pen and the shriveled apple. It found me. I felt the foil tear. The student looked at me, frowning at my lumpy, white-streaked surface and my weird ‘Linear Equations’ imprint. For a moment, I thought I would be cast into the trash bin, a failed experiment in thermodynamics. But then, he shrugged. ‘Chocolate is chocolate,’ he muttered. As he took that first bite, I realized that despite the heat, the pressure, and the indignity of the locker, I had fulfilled my purpose. I was still sweet. I had survived the middle school backpack, and in the end, that was a victory enough for any chocolate bar.
