Jesse Dylan interviews Dr. Christian Northrop & Yossi Ghinsberg down under.

In the 1990’s linguist Deborah Tannen told us why men don’t ask for directions and why women make statements into questions with her bestseller, You Just Don’t Understand; Women and Men in Conversation. Her latest, You’re Wearing That?: Understanding Mothers and Daughters in Conversation, tackles another fraught communication arena. It turns out that there could be just as much demand for guidance here; almost as soon as it was published last month the book hit number 9 on The New York Times bestseller list.
