Happiness and love in marriage is all about the small and simple things like holding hands. Many relationships, most probably, begin with the couple holding hands. It's simple but it conveys an intimacy and desire to be close both physically and emotionally. It's also really easy to hold hands and can be done in a variety of situations: in the car, on a walk, while watching television, reading a book, at church, during a meal (this is not meant to be an exhaustive list). Try holding hands today and see what happens. You'll like it, I guarantee it.
So, when was the last time you held hands with your spouse?
