Last week, I wrote about how we’re in a crisis of male friendships. Men in our 30s and 40s find it increasingly hard to build close friendships with other men. We might be surrounded by casual friendships, but few of us have guy friends who really have our backs, or who would jump into a fight for us. The good news is, we’re not alone. After I published the post, several guy friends texted me saying that it really resonated with them. Everyone agrees that we want closer male friendships, but so few of us actually know how to get started. Billy Baker, the author of the book which inspired this post, tried several ways to deepen his friendships. First, he tried calling up friends whom he hadn’t spoken to in years. But that approach feels weird to me. I don’t think I’d be able to hold a phone conversation with another guy for more than 5 minutes....
