For the typical human being, we have an awareness very early in life that many of the flatulence that exist our rear end makes a sound. Even more so, many of us find the sound to be entirely hilarious.
However, while that may be true for most people, there are also a lot of people in this world who can't hear, many of which were born that way. For the hearing impaired, not all of them realize that the farts that exit our bottoms make sound.
Anna Trupiano teaches a class of 1st graders and one of her students is deaf. It was on the day that this child learned that everyone could hear him fart that Trupiano realized she went to school for 8 long years to spend 15 minutes talking about farts. Amused and horrified by the realization, she shared her story on Imgur.
"Why is everyone looking at me?"
This is where it gets even better.
It's not going to work, though.
Farts are too complex.
Anna Trupiano may be mortified but the rest of us are laughing our butts off.
