My parents' marriage, that's who!
That's right -- as of October 4, 2009, my parents have been married for 40 years. (WOW.)
I'd love to speak for them and say they were all blissful, but since 32 3/4 of those years have included this feisty redhead, I'll hold off from doing that, and just focus on the enormity of forty years...of anything.
Day in, day out. In sickness and health. For better or for worse.
I don't really know anyone who has everyday memories reflective of a "Leave it to Beaver" or "Brady Bunch" type happy-go-lucky environment, but my sister and I did learn from our parents that sticking it out is the preferred method when it comes to marriage.
Congratulations, Mother and Daddy, on 40 years of ups and downs, good and bad, sickness and health, and showing us what it means to stick together for better and worse.
And, while we're at it, you're very welcome for being the good daughter. O;-)
