All right,” Marcus said, like he’d been looking for an answer like DNE his whole life. ” But I felt the opposite. While Ms. Saltzman blabbed on about how we’d be learning the formula for identical slopes, which would explain why these equations had no point in common and therefore no solution, I felt annoyed. It might sound strange, but the two things I used to trust most of all were my mother and math. Mom, because she was the kind of person who, if 29 she told you something, you knew it was true, and even if you were young, she didn’t act like you wouldn’t understand.

But now, I thought as I scribbled the stupid letters D, N, and E in my notebook, my mother’s acting like she doesn’t even want to know the truth, and now there are “solutions” that Do Not Exist. I was one of the last people to leave the room when the bell rang, and Damien was too, which made me feel like he was waiting for me.
