How is it possible? I think there's a trick to it with Ditto, but...
Jordan, my English teacher has FORGOTTEN we've had class quite a few times (be it English or Social Studies), and he sometimes comes in so late, although one time he thought we had class NEXT period one time, which in reality, was lunch time. Also, a lot of the tests he's given us on books are usually from the internet. It's rare that he gives us a test with his own questions on a book.
Which, I have to admit, I like.
