Men have been taught to avoid behaviors that get them labeled as "gay," a phenomenon called homohysteria. To make friends, however, men must transcend homohysteria. For example, Billy reached out to a friend he hadn't spoken to in a while, Rory, only to realize Rory moved to Vienna while enduring a breakup. In a radical gesture typically confined to couples in romantic comedies, Billy flew to Vienna to rekindle the friendship and support Rory.
