Teachers become teacher because they like to hear themselfs talk.

They end up with a group of students that are either nerds or jocks.

Why speed through notes that no student hears?

They pretend they are listening or so it appears.

In reality all they hear is white noise.

A few bla, bla, bla's inbetween the clock noise.

Teacher just do students a favor and print out the notes

So that students do not have to listen to boast. 

Highlight the answer that will be on the test

So that you can give your white noise talking a rest.
