AbbyQuilts,
It is interesting to me that someone younger notices. I was in such a fog when we were newly married that I didn't notice the couples with long lasting marriages. The last few years I have been looking around and have chosen someone to emulate - my parents have made it 67 years. With good health and blessings from above, perhaps my DH and I will get there, too.
It takes a lot of work, laughter and love. And every minute is worth the effort!
