I caught an interview with Tom Selleck and Donnie Wahlberg talking about the final episode of Blue Bloods, the long-running family cop show that aired its series finale Friday night. They talked about the emotions of recording the final scene, which gathered all the major characters around the dinner table one last time.

Apparently after the director yelled “cut” for the last time, no one spoke for awhile because they were sad about the finality of it all. They turned to Tom Selleck — always at the head of the table as Frank Reagan — and he admitted not knowing what to say but recited an Edna St. Vincent Millay poem that Wahlberg said brought the whole cast and crew to tears.

I can see why. It’s called “Love is not all.”

Love is not all: it is not meat nor drink
Nor slumber nor a roof against the rain;
Nor yet a floating spar to men that sink
And rise and sink and rise and sink again;
Love can not fill the thickened lung with breath,
Nor clean the blood, nor set the fractured bone;
Yet many a man is making friends with death
Even as I speak, for lack of love alone.
It well may be that in a difficult hour,
Pinned down by pain and moaning for release,
Or nagged by want past resolution’s power,
I might be driven to sell your love for peace,
Or trade the memory of this night for food.
It well may be. I do not think I would.
