<human>: So I sit down with my workbook and DVD. I pop the DVD into the player and the copyright warning comes up. So far, so good. 
Then the DVD menu appears, and the home menu is all of the featured signers introducing themselves using ASL. 
So I, like many of us, am accustomed to bullshit generic synthy guitary boring intro music, so I turn up the volume...nothing. I toggle mute-unmute...nothing. I make sure the speakers are plugged in...nope. I check the DVD submenu...and notice there are no volume/audio options. 
Then it hits me. 
It's an ASL instructional video. Why the hell would there be ANY sound? "HOLY SHIT I'M PART OF THE PROBLEM."
Now, some context: I work with disabled people every day. I work with an agency that contracts with the State of Oregon to help individuals with disabilities get back to work. I consider myself pretty culturally aware, but for one moment, I really had a "I DO have privilege I don't recognize" moment. 
Anyway... I gave myself the finger, signed "sorry," and got to work.

Provide a brief overview of the text.
<bot>: started a learning DVD for ASL,  got confused when there was no sound, had humbling moment of clarity.
