Dogeared

From Mary Karr's Lit:

If you lie to your husband--even about something as banal as how much you drink--each lie is a brick in the wall going up between you, and when he tells you he loves you, it's deflected away.

The head can travel a far piece while the body sits in one spot. It can traverse many decades, and many conversations can be had, even with the dead.

(What is dogeared?)
