Effect: Jack feels like he’s the kid in Home Alone with his mouth open and his hands on the side of his face. Cause?

From the text:

So I was kind of scrambling today, trying to take notes about what Ms. Rubin was saying (my handwriting is awful), when all of a sudden she started talking about the fifth-grade science-fair project, how we all had to choose a science project to work on.

While she was saying this, I was thinking, We just finished the freakin' Egypt project, now we have to start a whole new thing? And then in my head I was going, Oh noooooo! like that kid in Home Alone with his mouth hanging open and his hands on his face.
