I'm not sure how to feel about this one. It was well written and sprinkled with research, tips to maintaining friendship and a memoir of two friends who have been friends for 10 years. However, it was pretty boring. I wasn't engaged and couldn't relate that much to their friendship. I have a couple friendships I would categorize as "Big" and I thought this book was going to do a better job with tips on maintaining that. But coming to find out that they've only been friends for 10 years kind of seems phony to me. I'm not sure how these people can claim expertise on a category they've struggled on and off with for only 10 years. 

Lifelong friendship takes a lot of work and honest communication. Most people don't have the money or resources of the individuals in this book to implement some of the strategies they used (trips and therapy!). 

I think friendship is extremely personalized and each one needs it's own type of care. This book just wasn't it for me.
