reputation guard.

The reputation guards. They are like bodyguards but instead of guarding a body, they guard a reputation. 

And people will often approach me as though I am one. Did you hear what XYZ said? How can you defend XYZ? 

Here's the thing. Celebrities, friends, famous thinkers and most humans, don't need me to guard their reputation. They actually guard their own reputation. As do you. As do I. 

Just keep an eye out. You'll see how often conversations are always about someone else - and defending or attacking their reputation - so we don't have to talk about our own.
