The last of the podium points is volume. How loud or how soft.
Both ends of the spectrum can be annoying. They yeller or the low talker. Above is a Seinfield clip which will lead the poofy shirt incident. All because of a lowtalker. The clip below is from a new favorite, Pitch Perfect. The movie is wrong on so many levels but I laughed out loud as often as I gasped at what my eyes couldn't unsee. The young women in these clips is pitch perfect, literalty in her portrayal as the quiet girl.
