Oliver really appreciated that this professor did not talk so much at a time. It was easier for him to understand. He was actually able to listen to all, or at least most, of it without completely zoning out. But even if he did, he would have been able to copy off Ellery, since they were doing things with birthdays. Nice.
Oliver tried to do it on his own first. It was just his birthday. 14/2/2076. He put circles around those numbers. And, just to make sure he was right, Olly glanced over at Ellery's paper. Yep, it was the same.
