Valentine's Day is this Saturday and millions of people will be saying "I love you" to their sweetheart. But what if you had to describe how you feel about that special someone and you weren't allowed to use the word "love"?

That's what happened with Bob and Kim, a couple who have been together for 56 years. They were asked to describe their relationship and its longevity without using the word "love". They were able to do it in the most heartfelt way. And that's even better than candy, cards, flowers or dinner.
