Social norms are behaviors that are expected within society. When these behaviors are demonstrated in public people look on them with acceptance and satisfaction. When they are not people get confused and become annoyed.
I violated a social norm by dressing up in a skirt, nice blouse, and nice dress shoes, instead of active wear, and going for a run at the BYU indoor track. I headed over to the indoor track early in the evening and, carrying my purse with me, ran around the track. Lucky for me, there was a basketball sports camp going on at that moment, with hundreds of kids and dozens of BYU basketball players and coaches. As I ran around the track in my dressy outfit and carrying my purse, I got very strange looks and a few laughs. It was very uncomfortable and I could not help but laugh at how ridiculous I must have looked and at how I felt, which was very uncomfortable.
That was my experience violating a social norm.
