Q: Someone has done something objectively horrible to you, but your friend is still close to that person. How can you tell her how much that bugs you?

A: "It's up to you to distance yourself from the wrongdoer rather than expecting your friend to do it."
Anita L. Allen, professor of law and philosophy at the University of Pennsylvania Law School

"Her maintaining the friendship is convincing evidence that she isn't a true friend. Just tell her directly, and be prepared to downgrade her from 'friend' to 'pleasant acquaintance.'"
Jack Marshall, president, ProEthics
