Vindication

What if the subtlest temptation is vindication? Here's the scenario that has happened (gulp) more than once with me this month. Someone has done something that has upset me, so I want to go to my coworkers or friends and describe the situation then have them kindly concur that I was right so I can feel better about myself. Sometimes I'm wrong (like last time this happened), and sometimes I'm pretty sure I'm right (like in my current situation), but I wonder if it really doesn't matter if I'm right or wrong--that learning the grace to let go of the need to vindicate my own ego is more important than the satisfaction of people reassuring me that I'm good person.
