Los Angeles Times

The pair discussed dealing with grief in an interview on Anderson Cooper 360. “You wrote me a letter after my mom died, and in it you said, ‘I hope you find peace in your grief,’” Cooper said. “One of the things I’ve been thinking a lot about is how we don’t really talk about grief and loss. People aren’t comfortable talking about it.”
