When you’ve seen a movie as often as I’ve seen “It’s a Wonderful Life,” the lines you may not have noticed on first or second viewings pop out at you later.

One of the exchanges I noticed this past December, during my umpteenth watching of this holiday classic, happens when Mary sees George Bailey walking back and forth in front of her house, presumably getting up the nerve to knock on her door. “Are you picketing?” she asks, in a lovingly jocular way that would come to characterize their relationship.

I think of that line often as I walk Copper, an old doggie whose idea of a long stroll is making it one driveway down and back. First we turn right out of the driveway. After a brief mosey on that side of the yard and a careful sniffing of the planter at the foot of the mailbox, we turn the other way and stroll over to the forsythia and its band of encircling liriope, where there are more sniffs to be had, long lovely inhalations, as if Copper was about to swill a fine wine.

Sometimes we repeat this backing and forthing several times before we go inside. Does it feel like picketing? Absolutely! All we need is a sign: “More meat, less kibble!”
