Exactly the Same

I don't know how the two of you did it!" Mrs. Marsh said in exasperation. "Both of you got the exact same score, and the exact questions wrong, but you were both sitting on opposite ends of the room. How did you do it?"

Mark and Bryan looked at each other and then back at their calculus teacher, "well, we are twins," Bryan said, but swallowed the rest of his statement when she shot his a glare.

"Mrs. Marsh," Mark spoke up softly, "the most simple answer is that we study together, so what one of us know, the other also knows. We drill and drill, if we didn't get it right it's because we didn't study that hard enough. Simple as that," Mark finished just as softly as he had started.

Mrs. Marsh looked from Bryan's smiling face to Mark's quietly composed face, shrugged and shooed them out the door.
