The best apology, I think, was from my husband, Steve, who slept with a close friend of mine decades back, when we were committed to being life partners but not yet married. And many of the factors that made Steve's apology so healing are universal. One important thing is that he confessed to the affair, rather than my discovering it. He looked deeply into his own history in terms of why this happened, but he never used that history as an excuse.

There are some things for which there is no apology, and on the question of slavery, there is no adequate apology for ripping people out of their homeland and bringing them here in chains. There is no adequate apology for the ongoing horrific legacy of racism.

deception and 'con games' are a way of life in all species and throughout nature. Organisms that do not improve their ability to deceive - and to detect deception - are less apt to survive.

The first world we find ourselves in is a family that is not of our choosing.

Anger is a signal, and one worth listening to.

Silence can pose a greater threat than the difficult truth.

Throughout evolutionary history, anxiety and fear have helped every species to be wary and to survive. Fear can signal us to act, or, alternatively, to resist the impulse to act. It can help us to make wise, self-protective choices in and out of relationships where we might otherwise sail mindlessly along, ignoring signs of trouble.
