When a girl in my fourth grade class brought in an assortment of cupcakes for her birthday, I chose red velvet. My teacher sat the cupcake on my desk, and instructed all of us not to eat them until every person had one. I sat patiently. My time had come. What were a few more minutes? Once we got the go ahead, I reverently peeled back the paper surrounding the bottom of my cupcake. Then, I licked the delicious buttercream frosting from my fingers. Finally, I took a healthy, but not greedy, bite. At first, all I tasted was sugar, and that was enough. Then, I tasted something else. What was that? It was sweet, but also…metallic? Acidic? In any event, I didn’t like it. In fact, I opened my mouth and let the mostly chewed up cupcake fall back into the wrapper like the trash it had revealed itself to be. My teacher walked quickly over to me with worry in her eyes.
