How often do we find ourselves worrying about what others will think of us before entering into a benign, low-stakes social interaction? How often are we worrying while we are in one? How often do we worry that others are thinking about some foolish but otherwise irrelevant thing we said or did in the past? How often are we doing or not doing things, buying or not buying things, trying or not trying things because of our concern over how others we barely know and are barely affected by will see us?
