When people leave books upturned on their spine to save their spot. Or when they curl a paperback book around like a magazine and break the spine. And when they dog-ear pages, rather than use a bookmark.

i cant stand the sound that flip flops make when dragged across the floor. most folks dont even realize that theyre doing it. that makes it even more annoying.

When someone sneezes more than three times. It's like "I BLESSED YOU ALREADY!! WHAT DO YOU WANT?"

My father sneezes at least three times, every time. So does my twin sister. Sometimes they sneeze like six times and it's aggravating.
