Alex is most definitely a robot. I’m sure of it.
You used “than” twice in the first paragraph when it should have been “then.” Other than that, nice addition. Good description of the teacher.

Fixed it, thanks for pointing that out. Robots frighten me, for serious.

At least he’s happy about their moronic stupor. Great portrait of a chemistry professor. Makes me want to put my favorite chem professor into a story!

I love how you described the teacher. Especially with the glasses. And how you described the students as they appeared to him as a mass of gawking faces clouded in ignorance. one question although, why was the teacher so upset? What was causing his face to be all twisted in a sneer?

To the students the teachers smile looks like a sneer, he’s assuming they are all ignorant and that he has the answers to all their questions… so his smile looks a bit derisive I guess
