I Told A Little Lie In Class Today

Today I told a little lie in class that's been eating at me ever since. My professor asked who had submitted the late assignment and everyone was looking my way, so I just said it wasn't mine even though it was. It felt really small at the time, like the kind of thing that wouldn't matter much in the grand scheme of things. But now every time I see him, I feel this tiny knot in my stomach. I know if I were honest and owned up to what happened, there would be no lingering awkwardness. But it's too late for that now, isn't it? Plus, there's always the fear of getting into more trouble or looking bad in front of everyone. So here I am with this little secret weighing me down every day until exams are over and I can move on. Part of me wishes my classmates wouldn't be so quick to assume things about each other all the time.
