Chapter 4: One Last Letter
Trigger warning: referenced domestic abuse
_________************_________
Three weeks into the school year, Shera decides to test him. That’s what he thinks it is anyway.
Cloud is tapping his pencil against the table when the knock comes. He takes a deep breath as he gets up, exhaling slowly before he answers.
Tifa stands on the other side of the door, one hand letting her ponytail down. Her other clutches the strap on her shoulder, her eyes fleeing his after a few seconds. Her jaw is tight as she chews on her lower lip. Cloud clears his throat.
“Shera told you she’s stuck in a meeting, right?”
Tifa nods. Her gaze doesn’t meet his, instead remaining fixed on the door frame. “You’re supposed to tutor me?”
Cloud moves out of the way to give her space. “Yeah. Come in.”
There is a moment of hesitation before she quickly shuffles past him. Cloud trails her, making sure not to follow too closely.
“Want anything to drink?”
Tifa slides into the breakfast nook and deposits her bag next to her. “Water?” Her voice is uncertain, as if she doesn’t want to impose even though he just offered.
He grabs two glasses and fills them with ice and water before joining her. “It’s pretty hot outside, yeah?”
“Yeah. Thanks.” She lifts the glass to her lips and uses the end of her sleeve to wipe her forehead. Tifa doesn’t continue the small talk, so he drops it and opens his math book.
“So, what was the last thing you did with Shera?”
He wants to get started as soon as possible so they have something else to focus on other than the awkward tension. His uncle’s warning rings in his head, and he wants to be nice—Tifa doesn’t seem so bad. He has to see her on a regular basis, and she hasn’t given him any reason to be a jerk, unlike a lot of other people he’s met since coming here. Her anxiety is so palpable that it rubs off on him, but it also makes him want to create a comfortable atmosphere for her to relax in.
Tifa fishes out her textbook and pencil. Her fingers tap the pages of her planner as she scans it to find her last lesson.
“Accuracy and precision.”
Cloud hums, flipping to the correct chapter. “Did you go over bias yet?”
“I think you’re a day behind where we are in class, so I’ve already done this.”
Tifa puts her glass down a little too hard, and he glances up from his notebook.
“Sorry, I didn’t mean for that to sound…”
“It’s fine.” Her hand runs through her thick hair again, shifting most of it over one shoulder.
“I just meant that, since we’ve done this, it should be easy to teach you.”
“Okay.” Her voice is strained, begging him to move on.
Cloud fights the urge to scratch the back of his head. His jitters will make things worse.
“Okay then, uh…” He’s never been a tutor before and wasn’t sure if he even had it in him to teach anyone. Cloud isn’t the most patient person, but that’s because he doesn’t like to deal with other people’s shit. This isn’t the same, and Shera has put her faith in him. He only has to take it one step at a time, beginning with the last thing she remembers.
“Can you tell me about accuracy?”
Tifa’s brow pinches as she puts her eraser between her teeth, her eyes sweeping over her notes. “It’s… it’s how close the measured values are to each other?”
The confusion etched into her features fades into dismay as he shakes his head. Cloud turns his notebook so it is facing her, his finger near the top of the page.
“That’s precision,” he says, skimming over the lines. “Accuracy is how close any individual measured value is to the true value.”
She gnaws on her lower lip again as she follows his hand, reading his notes. “I don’t really… get how they’re different,” she mutters, and she sounds like she’s ready to give up on the topic already.
Cloud sits back in the booth. It’s easy enough to him, but how to show her…?
He recalls something Shera showed in class.
“Are you a more visual learner?”
Reaching back over the table for his notebook, he draws a chart with several lines and numbers, before turning it back to her.
“Okay, let’s say the actual, or true, value is 20.” He points to the middle of the line, then drags his finger across. “17 is one of your values. Compared to the other values, since it’s closer to the true value of 20, it’s the most accurate.” Cloud looks up at her, giving her time to ask a question. She only stares at the number line, so he continues. “These values — 10, 11, and 12 — are all relatively close together. So they are more precise.”
Her face doesn’t change; her brows remain pushed together, her mouth set in a firm line. Cloud ponders another tactic, drawing several circles onto the paper.
“Think of these as targets. Bullseye in the middle, right?” She affirms with a curt nod. Cloud draws a few dots spaced around the center. “These values are close to the bullseye, so they’re more accurate.” On the second circle, he draws a cluster of dots near the top of the target. “And these values are more precise because they’re so close together. But they aren’t very accurate because they’re far away from the middle.” Cloud creates a group of dots huddled over the center of the third circle. “These are both accurate and precise because they are all close together and they are close to the bullseye.”
Tifa’s eyes widen as he goes through the lesson, and she scribbles in her notebook. Cloud waits for her response, and when she looks up, comprehension shines on her face. She pushes her notebook forward for him to see she’s replicated his number line with some additions.
“So, if 20 is the true value…” she starts hesitantly, glancing at him, “and I have values of 17, 18, and 19, those are precise because they’re close to each other. And they’d be accurate too?”
The corner of his mouth twitches upward. “Because…?”
“Because… because they’re close to the actual value. Closer than my other values of 10, 11, and 12.”
Cloud smiles. “Yeah, you got it.”
Relief washes over her, and the tension melts away as she shifts back. Her lips curve just slightly in satisfaction, but it’s enough that Cloud notices how different her face looks when she isn’t so tense. Her eyes soften, the creases around them diminishing. As her jaw slackens, the roundness of her cheeks becomes more apparent. For the first time, Cloud sees something other than her anxiety - a gentleness that almost startles him. Through their sparse interactions, he was beginning to think she’d never allow herself to unwind around him. Cloud takes a bit of pride in not only getting through the hurdle of the first lesson, but in making her feel a little more comfortable.
