The disappointing grade settled like a lead weight in Emily’s stomach. She pushed her untouched plate of pasta away, the dining hall's cacophony fading into a muffled hum. She found herself drifting towards the campus pond, where she'd spent countless afternoons as a child, skipping stones. The rough, cool feel of the stones in her palm transported her to those younger days. The vibrant greens of the trees reminded her of the endless summer days, the feeling of pure, unadulterated joy that seemed so far removed from the pressures of her current life.
