Cover art for Feet of a Liar lyrics by David Vandervelde

I think this song is about two people in a relationship. one has wronged the other, and he/ she wants to talk about it. the "liar" wants their significant other to know it's all right to get angry, but not to judge too harshly, because their misdeed might have been necessary for the continuation of the relationship.
