"Michael was glib, in my opinion. It could be the truth or it could be what he thought I wanted to hear.

But then it dawned on me that if he were not so handsome, people might well see him differently and accept everything he said at face value."

 

Because what I think it's saying is that pretty people are liars.  amiright?
