And the strange thing is: I want to know the answer. The fact that he wouldn’t care makes me want it more.

“Sure,” she says, not sounding sure at all.

I find it hard to look at her. I know from experience that beneath every peripheral girl is a central truth. She’s hiding hers away, but at the same time she wants me to see it. That is, she wants Justin to see it. And it’s there, just out of my reach. A sound waiting to be a word.

She is so lost in her sadness that she has no idea how visible it is. I think I understand her—for a moment, I presume to understand her—but then, from within this sadness, she surprises me with a brief flash of determination. Bravery, even.

Shifting her gaze away from the floor, her eyes matching mine, she asks, “Are you mad at me?”

I can’t think of any reason to be mad at her. If anything, I am mad at Justin, for making her feel so diminished. It’s there in her body language. When she is around him, she makes herself small.

“No,” I say. “I’m not mad at you at all.”

I tell her what she wants to hear, but she doesn’t trust it. I feed her the right words, but she suspects they’re threaded with hooks.

This is not my problem; I know that. I am here for one day. I cannot solve anyone’s boyfriend problems. I should not change anyone’s life.

I turn away from her, get my books out, close the locker. She stays in the same spot, anchored by the profound, desperate loneliness of a bad relationship.

“Do you still want to get lunch today?” she asks.

The easy thing would be to say no. I often do this: sense the other person’s life drawing me in, and run in the other direction.

But there’s something about her—the cities on her shoes, the flash of bravery, the unnecessary sadness—that makes me want to know what the word will be when it stops being a sound. I have spent years meeting people without ever knowing them, and on this morning, in this place, with this girl, I feel the faintest pull of wanting to know. And in a moment of either weakness or bravery on my own part, I decide to follow it. I decide to find out more.

“Absolutely,” I say. “Lunch would be great.”

Again, I read her: What I’ve said is too enthusiastic. Justin is never enthusiastic.

“No big deal,” I add.

She’s relieved. Or, at least, as relieved as she’ll allow herself to be, which is a very guarded form of relief. By accessing, I know she and Justin have been together for over a year. That’s as specific as it gets. Justin doesn’t remember the exact date.

She reaches out and takes my hand. I am surprised by how good this feels.

“I’m glad you’re not mad at me,” she says. “I just want everything to be okay.”

I nod. If there’s one thing I’ve learned, it’s this: We all want everything to be okay. We don’t even wish so much for fantastic or marvelous or outstanding. We will happily settle for okay, because most of the time, okay is enough.

The first bell rings.

“I’ll see you later,” I say.

Such a basic promise. But to Rhiannon, it means the world.

At first it was hard to go through each day without making any lasting connections, leaving any life-changing effects. When I was younger, I craved friendship and closeness. I would make bonds without acknowledging how quickly and permanently they would break. I took other people’s lives personally. I felt their friends could be my friends, their parents could be my parents. But after a while, I had to stop. It was too heartbreaking to live with so many separations.

I am a drifter, and as lonely as that can be, it is also remarkably freeing. I will never define myself in terms of anyone else. I will never feel the pressure of peers or the burden of parental expectation. I can view everyone as pieces of a whole, and focus on the whole, not the pieces. I have learned how to observe, far better than most people observe. I am not blinded by the past or motivated by the future. I focus on the present, because that is where I am destined to live.

I learn. Sometimes I am taught something I have already been taught in dozens of other classrooms. Sometimes I am taught something completely new. I have to access the body, access the mind and see what information it’s retained. And when I do, I learn. Knowledge is the only thing I take with me when I go.

I know so many things that Justin doesn’t know, that he will never know. I sit there in his math class, open his notebook, and write down phrases he has never heard. Shakespeare and Kerouac and Dickinson. Tomorrow, or some day after tomorrow, or never, he will see these words in his own handwriting and he won’t have any idea where they came from, or even what they are.

That is as much interference as I allow myself.

Everything else must be done cleanly.

Rhiannon stays with me. Her details. Flickers from Justin’s memories. Small things, like the way her hair falls, the way she bites her fingernails, the determination and resignation in her voice. Random things. I see her dancing with Justin’s grandfather, because he’s said he wants a dance with a pretty girl. I see her covering her eyes during a scary movie, peering between her fingers, enjoying her fright. These are the good memories. I don’t look at any others.

I only see her once in the morning, a brief passing in the halls between first and second period. I find myself smiling when she comes near, and she smiles back. It’s as simple as that. Simple and complicated, as most true things are. I find myself looking for her after second period, and then again after third and fourth. I don’t even feel in control of this. I want to see her. Simple. Complicated.
