Great. In the beginning of the book, Goodwin demonstrates, through letters between men, just how screwed up we have become about friendships. It was common for hetero men to express love and longing towards each other....one reason, I think, was because they weren't scared of being accused of being homosexuals. But this is a problem I see between all people in present day America. We only allow ourselves to express these feelings when feeling romantic love. I think it damages us that we don't feel free to express deep, loving feelings towards any loved one.
There were, of course, numerous other great things about this book.
