I took roll as per normal, but I noticed something fishy. I should have had 27 students. I had 28.
I must have counted wrong. The seating chart may have been inaccurate. Nope. There was an extra student in class.
Which begs the question: Why? It wasn't a "fun" class. The students were well-behaved. They had an essay to write, which they did.
It took me some time to identify the interloper. He sat in the corner, trying to look busy.
By this time, it was nearly the end of the period. I confronted him. He claimed to be a new student. Said his name was Ned.
(New students always identify themselves as soon as they walk in the door, primarily because they don't know where to sit. And as I had access to the online attendance, I know he wasn't on my roll sheet. Not even as a new addition.)
I have no idea what he got out of it. I know that his sixth period teacher marked him absent. So, since he wouldn't show up anywhere else on campus officially, he'll be marked truant. Which eventually will get him a Saturday detention at minimum.
Lots of downsides. I don't see the upside.
On Monday I was back in the class. "Ned" walked in again. Took a look around. "Oh, this isn't my class." And walked out.
A minor victory.
