Our car’s outside temperature had registered 106 on Saturday as we climbed out to go to an outdoor wedding ceremony in Virginia. I’m sure I’ve been hotter in my life; I just can’t remember when. As the wedding guests squirmed in their seats in search of a whiff of a breeze, the bride entered the patio. Ebullient and radiant, her smile infected us all. What heat?

Besides the unseemly temperatures, this was a memorable wedding for another reason. It involved three mothers: the bride’s, the groom’s, and the groom’s stepmother. A recipe for in-law disaster. Yet it wasn’t. And to this I not only credit the bride, who showered all three moms with attention and appreciation, but the groom’s mom as well. (Okay, full disclosure: I’m a friend of the groom’s mom.)

Seriously, a lot could have gone awry. The children’s two mothers were as different as…well, you decide. One is a native New Yorker, the other a Midwesterner. The ceremony included a pastor who wore a robe embroidered with a gold cross and a tallis (a Jewish prayer shawl) draped over his shoulders. A unity candle was lit. A glass was broken. A marriage forged.

And during the reception, everyone danced. Naturally, the bride and groom. But the three moms as well. The differences between the families of the bride and the groom were celebrated rather than judged. The inclusion of the groom’s step mom was welcomed, rather than merely tolerated.

When we all raised a glass to toast the young couple (great toasts, by the way, by the bride’s sister and groom’s brother!) I actually was thinking at the time: Way to go, moms. You’ve set an example for the young couple as well as for all of us.

It’s not about us moms, it’s about our kids.
