That week I put on my sweater and went to school, feeling quite pretty.
I sat in class anxiously biting the side of my cheek. The teacher had been explaining a new concept for the past hour or so and I still didn't understand a word he was saying. I rubbed my eyes and squinted at the board, as if hoping this would trigger some sort of magical understanding.
Afterward, my friends talked about how easy the new chapter was. I shut my mouth and slipped my hands into my sweater pockets.
I'm so stupid.
It felt wrong to think that, but it had to be true. I didn't understand the concept and everyone else did. So I had to be stupid. Suddenly conscious of everyone, I glanced around and shoved my hands into my pockets.
That's when I subconsciously started fingering the thread inside my pocket.
