You've been through and are going through quite a few transitions with moving, jobs, kids etc. That is a lot for anybody to handle. Keep that active and open communication going. Good luck!

As far as pinterest I don't really have much of an opinion. My wife mostly uses it to find recipes or craft ideas. It's never bothered me much. Now how much time she spends on facebook and blogs is another subject, but I've been working on spending less time watching sports too. We've all got things we could do better.

Social media as a whole is a very interesting thing. I think we still have no idea the impacts it's going to have on society. It can be good and bad depending on how you use it. It can be really addicting and troublesome for some people though. Your wife could certainly be doing a lot worse things than doing relief society stuff on pinterest!
