Feeding time

It is a matter of choice.

For the lack of a better term we might refer to this duality as, "our good side" and "our bad side".

In keeping with that thought, when asked to describe himself, a man once said, 

"Inside of me there are two dogs".

"One of the dogs is mean and evil".

"The other dog is good".

"The mean dog fights the good dog all the time".

When asked which dog wins he reflected for a moment, and then he said,

"The one I feed the most."
