I finished reading The Perfect Paradox. It was the perfect book for me, spending many chapters discussing the peculiarities of the purple paradox. It labelled a purple paradox as something that looks impossible but is actually closer to "following a different set of laws than we're used to," while a regular paradox is the theoretical phenomenon which is considered to be impossible.
The student in question who left the book was absent today. I admit, by this point, I'm getting a little bit on the paranoid side. There have been a lot of absences lately; Edward still hasn't shown up. But, I tell myself, it's winter. There's a flu going around; teachers haven't been showing up, either. So I just taught the class their lessons for today, trying my hardest to resist the urge to introduce the theoretical equations I had been reading about.
On the way home, I noticed the bakery was closed up and surrounded with police tape. The door was open by just a crack, and I'm sure I saw someone wearing some kind of mask inside.
