"Determine to guard your mate's secretes (unless they are dangerous to them or you) and to pray for them. Talk with your spouse, and resolve to demonstrate love in spite of these issues. Really listen to them when they share personal thoughts and struggles with you. Make them feel safe."
This was a hard one to really get my head around. I read & re-read the chapter, and it seemed to be about trust. Specifically, being trustworthy to your spouse. I found the caveat in this "dare" kind of interesting. I imagine someone asking their wife to tell them a secret, and getting something like "Thou shalt get kings, though thou be none," or "Beware the ides of March."
None of that really helped me figure out what I was supposed to do.
Anyway, I talked to Nicole about this, and she offered to share secrets. Of course, her secrets were things
like "I go out to eat when you work on the weekends." Nothing too exciting.
