“Physical chemistry applies theories of physics to study chemical systems, which include reaction kinetics, surface chemistry, molecular quantum mechanics, thermodynamics, and electrochemistry.”

I smile this dazzling smile, one that competes with the overhead lights and the sun beating in the windows. I am going to blind her with this fucking smile so she won’t ever be able to see my dad again. A girl two chairs over is grinning at me, chin in her hands, but the others look confused and a little disappointed. The Guy Who Seems to Be Damario says to his desk, “Man.” And I can tell in that one word what a letdown I am.

“Actually, I think that’s my favorite, electrochemistry. There’s just something about a good chemical reaction, am I right?” And then I wink at Monica Chapman, who—for the next twenty seconds—goes speechless.

As soon as she can talk again, she gives us a pop quiz to “judge our aptitude,” but really I think she’s doing it to mess with me, because she grades them at her desk and then says, “Jack Masselin. Pass these back.”

And it is on.

I get out of my seat and walk to the front of the room and take the quizzes from her. And then I stand there for a minute, trying to figure out what to do. The class is looking at me as I look at them. There are four kids who are definite IDs. Three, I’m fairly sure I don’t know and am not supposed to know (but I’m not completely, totally sure). Eight are in the gray zone—better known as the danger zone.

Now, I can march up and down the aisles, trying to match the names of people I know with the faces. I can take all the shit that would be thrown at me as soon as it’s clear that I don’t know who everyone is. Prick. Dumbass.

Or I can do what I’m doing now—hold up the stack of papers and say, “Who here really wants to see what you got?” It was a pop quiz, after all, so it’s not like any of us prepared for it. For good measure, I flip through the pages, and most of the grades are C, D, C-, C. As expected, no one raises a hand. “Who would rather take this opportunity to promise Mrs. Chapman you’ll do better from here on out?” Almost all hands go up. These hands are attached to arms that are attached to torsos that are attached to necks that are attached to faces, which swim at me, foreign and unrecognizable. It’s like being at a costume party every single day where you’re the only one without a costume, but you’re still expected to know who everyone is.

“If you’re interested, I’m going to set them right here.” I drop them onto an empty desk at the front and take my seat.

When the bell rings, Monica Chapman says, “Jack, I’d like a word with you.”

I walk right on out the door like I don’t hear, and go directly to the school office, where I tell them I need to change to the other advanced chemistry class, even though it’s taught by Mr. Vernon, who is at least one hundred and deaf in one ear. The secretary starts in with “I’m not sure we can switch you because we’ll have to reorganize part of your schedule …”

For a minute, I’m tempted to say forget it, I’ll stay right where I am. Believe me, I’m more than happy to torment Monica Chapman for a semester. But I think about my dad losing his hair, about how paper-thin the chemo left him, about how frail he looked, like he might crumble away in front of us. I remember what it felt like to almost lose him. There’s a part of me that still hates him, that maybe will always hate him, but he’s my dad, after all, and I don’t want to hate him any more than I already do. Besides, I actually like chemistry, and why should I ruin that for myself?

I lean on the counter. I give the secretary a smile that says I’ve saved this up for you and only you. “I’m sorry if it’s inconvenient, and I don’t want to be a pain in the ass, but if it helps, I know we can get Mrs. Chapman to sign off on this.”

I decide to skip lunch. The thing that comes after it is gym, and I don’t think there is a heavy girl on this planet, no matter how secure she is, who doesn’t dread gym.

In the grand scheme of things, today could be worse. No one’s banned me from the playground. So far I’ve only been mooed at and laughed at four or five times, and stared at a couple hundred times. A lot of people haven’t looked twice at me, and a lot of them are treating me like anyone else. I’ve made at least one, maybe two, potential friends. I haven’t had a single panic attack.

But the hardest thing is something I didn’t expect—seeing people I used to know, people I grew up with, and knowing that while I sat in my house, they got older and went to school and made friends and had lives. It’s like I’m the only one who stopped.

So I don’t feel like eating. Instead I sit outside the cafeteria in the parking lot and read my favorite book, We Have Always Lived in the Castle by Shirley Jackson. It’s about a girl named Mary Katherine Blackwood. Most everyone in her family is dead, and she lives with her sister, holed up away from society, trapped in her house, not by her weight but by a horrible thing she did once upon a time. The people of her village tell legends about her and are afraid of her and sometimes sneak up to the house to try to catch a glimpse of her. I’m pretty sure I understand Mary Katherine in a way no one else does.

I read for a few minutes, and then I close my eyes and tilt my head back. It’s a warm, bright day, and even though I haven’t been housebound in a while, I don’t think I’ll ever get enough of sunshine.

Gym is worse than I imagined.

Of course it’s Seth Powell who says, “There’s this game I read about.”
