<p>I remember I had a grad school class with a prof who could not relate at all to the class. No one could understand what he was trying to say - and the prof was a native English-speaking American. </p>
<p>One day, a few students from the class were talking about how much they hated the prof. A student from Taiwan turns around and says “You mean you don’t understand him either?!!” There was such a look of relief on his face when he realized that it was not the fault of a language barrier - that the guy was just an awful prof.</p>
