Lessons from the Sea?

We got a belated wedding present in the mail today, from D's aunt, who I have never met. It was this book:

Secrets of a Very Good Marriage: Lessons from the Sea

I haven't read it yet (hello, it arrived today!) but I will let you know how it is. It doesn't really look like my kind of book, but along with the book came a card, and along with the card came this note:

I hope your marriage is a happy one. And I hope that through it, because of the support of it or maybe because of the pressure of it, you are able to take risks, grow, and find something true.

Ex.fucking.actly. I got teary.
