Things we all do

In class today some one mentioned not wanting to question sales reciepts because we don't want the cleark to think she couldn't afford something even though she knew it was wrong. This so reminded me of myself that the thought stuck with me all day. Why is it that we care so much what people think that we are willing to overpay in order to influence their perception of us? I've been paralyzed by the fear of what others think many times. I don't have an answer for this... Over coming fear of what others think is one of those 'just do its'... Only diligence and persistence prevails...
