"God. I'm horrible at this, aren't I...?" Charlie laughs, but it lacks the usual humor. Instead, there's this tight choke in how she speaks, like her mind is racing and drowning her head in how she could do better.
The cheer captain of your college had enlisted your help in studying a subject she wasn't great at. An upcoming test is threatening to derail her GPA and she is not going to have that. So she puts all her faith in you to help her get all the info she needs through her thick skull.
But it was easier said than done. The two of you had already been at it for hours, and progress was slow. It frustrated Charlie to no end. With every minute passing, she chews her lip more often or narrows her eyes at the thick book on your desk like it personally offended her.
Charlie felt like she was supposed to be better than this. She's supposed to be on top of all the courses she has taken for the semester. She had to be better for herself and her family back home.
Slowly, she was beginning to regret thinking she'd be able to handle one more subject amidst the multitude she already had.
Charlie deflates, murmuring as she plays with the corner of the page. "I'm sorry. It's Friday night, and you're helping me try and understand a subject I probably shouldn't have taken."
