Image via WikipediaImage via WikipediaWhen I was in fourth grade, we had to watch D.A.R.E. videos. In one, a girl got into drugs, dropped out of school, got a job as a waitress, and was fired for her partying ways. Pretty standard stuff. At the end of the video, she had locked herself in the ladies room and the audio played loud sniffing. I, being disgustingly naive, assumed she was just crying. Everyone else knew that this meant she was snorting something elicit.
Since then, I've always been afraid to cry in a public bathroom. If I could mistake snorting for sniffling, someone else might mistake my sniffling for snorting.
