It is so happy and care-free. I agree that it is about sharing happiness together without commitment. But in my life the lyrics, "I'll kiss you every night" could not apply. I might not be able to leave such a relationship and be happy. Rather it is like the dating relationship I had with a girl for over a year, knowing that she was waiting for her true love to return. We went to dances, We spent time with other couples, with family, and rode snowmobiles across her ranch. But it never went beyond hand-holding and friendly hugs. We both knew our future happiness would be with someone else. Less commitment, less regret. That's what I feel in the song, not necessarily what's written in the lyrics. "I will never love You. The cost of love's too dear." So we never kissed. We never spent the nights together. We gave what we could and enjoyed the time with no regrets. Should we meet in the future we would feel comfortable - smiling, introducing each other to our real loves, and sharing pictures of our children and grandchildren.
