American Classes

Have you ever had a class cancelled because there were too few students in class? Well, it happened to me today. I was the first student present in class. (I mean first person actually...cuz professor was not there yet). Anyway, it turned out that out of a class of about 30 students, only 11 students attended today's class! Don't really know why they didnt attend...but personally if I don't attend his class, it will be.... 1. Since the final exam is not going to be on his lectures/textbook, why attend the class? (The final exam would be on the 3 articles that he distributed in class during the semester. I wonder why I bought the textbook for) 2. Since you already know the lectures are not going to be in the exam, why attend classes? 3. Bascially since you won't pay attention in class cuz you know lecture materials aren't important, why attend the class? 4. Since lecturer is not going to take our attendance, why attend the class? 5. Since you are going to sleep in class, why attend the class? Side note: I have never missed any of his class. :)
