The Foils (I first introduced them in "Meet the Foils") recently visited the city for the weekend, two of their four kids in tow.

The Foils are a lovely couple, and they have achieved everything Rob and I cannot — the gaggle of happy and healthy children, the strong family bond, and the clear mission to ride the ups and downs in their marriage, come what may. I can't really relate to all that togetherness, and it gives me serious doubts about my marriage.

Rob and I took charge of the kids Saturday while their parents attended a wedding. We went to the zoo, indulged in ice cream, rode the train (to kids from the country, subways are wondrous), and enjoyed a festive Mexican dinner. An incredible day.

I expect the kids talked about their city adventures during the entire seven-hour ride home with their parents.

Of course, kids must feel safe and secure to enjoy themselves in new territory. That's not easy when you're not their parents. So it's all the more precious that Rob and I pulled that off together. But I still don't want to have kids with him.

I'm in my mid-30s with a bit of time to spare, so perhaps I will be a mother in the next chapter of my life?

Or so I've been hoping. Yesterday a friend in the 30th week of her second pregnancy said she must endure more monitoring and tests this time around because she is considered by the medical establishment to be of "Advanced Maternal Age." What? I guess sooner than later, I need to move on.
