Seriously, don’t chew your food with your mouth open.
There is no reason for me to be able to see the food in your mouth being chewed. There’s also no reason for me to be able to hear you chewing your food.
What are you?
Some kind of dog?
Have you never been taught that basic rule of polite and civilized society?
Is your name Romulus or Remus?
Have you no lips?
If none of the above apply to you, then you have no excuse. Close your mouth when you’re chewing your food.
People chewing with their mouths open, is a huge pet peeve of mine. It drives me up the wall. I can tolerate it to a certain degree in little kids, but I cannot tolerate it from adults. Specially from adults that I have to sit next to in a closed door meeting.
Don’t even get me started with mouth breathers.
