They're too happy. My wife and I were playing tennis this weekend next to a couple of 35-year olds. They were adorable. Being so sweet to each other. Constantly giggling. I went up to the net and asked my wife what she thought their relationship was. She instantly replied, "Oh, they're not married." I had thought the same thing, and for a while I felt bad about that. But, then I realized that the only difference between them and us is that we're comfortable around each other. There's no awkward tension. We still go out and have fun. Love spending time with each other. Laugh. There's just no pressure. But, it did make sad that nearly all relationships start like those giggling 30-somethings, and that less than half stay laughing.
