Ashley had nothing to say, not knowing about any of these games. He was pretty sure muggles had cards, but he didn't know of any of the games they played with them. So he tried to come up with some games he knew of, and try to picture a muggle version of them. And that wasn't working either. Giving up on all of that, he decided instead to just take notes, also trying to get the names on those games that had come to be stacked near the professor so he could take those down too.
