The Conversation that Ended an Argument

While in the middle of a semi-colorful argument last week, 

after I had allegedly given him a bad look:

TLI:  See!  You can't even listen to what I'm saying.

Me:  What?  I didn't say anything.

TLI:  It was your body language.

Me:  So, you're a body language expert now?

TLI:  Well, I am a Communications major.

He was 100% serious.  Utterly ridiculous.  I erupted in laughter.
