WARNING: If you don't like gum chewing and/or mouth sounds. don't watch this. I have misophonia and could only tolerate about 1.258 seconds of it before I had to stop it. *Shudder*
This video is very simple. I'm all up in the microphone with my gum chewing the entire time. You may be able to hear the scratching of the fine-tip Sharpie markers on the page. I honestly don't know. The sound of gum chewing sends me on a misophonia-fuled rampage, so I didn't listen long enough to find out.
