Elisa and Nathan are the parents of an adorable 18-month-old named Sadie. Like me, they live in Brooklyn, though I don’t know them. I do know a friend of Elisa’s, but even with 100 more degrees of separation this situation would make me want to do something.

A little over a month ago, Nathan was diagnosed with stage 3 colo-rectal cancer. That’s bad.

Nine days later, Elisa was diagnosed with stage 4 breast cancer. That’s unbelievably bad.

Both of them have advanced cancer. Both of them. And they have a toddler.

I have no idea what I would do in their shoes (I don’t think I can even let my mind go there), but so far they’ve been holding up with tremendous grace and good humor. And their friends have done what I’d like to think my friends or your friends would do when faced with something like this: They’ve set up a web site for donations. Fighting cancer is expensive, and fighting two cancers simultaneously is mind-boggling, even without the they-have-a-toddler factor.

Thanks.
