I find it hard sometimes to think of others and their weaknesses.  I always assume that others are so sure of themselves and their decisions.  Meanwhile I have always feared that others think the worst of me as we interact.  Case in point:  I look in the rearview mirror and see a vehicle.  I don't know who is in the vehicle, but I automatically assume that they don't like me or my driving. 
Strange, huh?  But that's how it's been my whole life.  I realize that I am a good mom, a decent athlete, and an awesome wife.  (Not such a great home maker though...), but for some reason I assume that everybody else thinks otherwise. 
Perhaps all of us have some part of this syndrome inside of them.  But then again they probably all think that I am a little weird...
