DUNMORE HEIGHTS — The Dunmore County Historical Society unveiled a bronze plaque Saturday marking the precise location where, at approximately 9:40 p.m. on October 17, 1987, a man named Gary quietly decided to leave a housewarming party without telling anyone.

The marker, mounted beside a coat rack in the Pruitt family’s front hallway, reads: “Here, a man found his jacket and kept walking.”

Society president Marjorie Kellbrook-Ames said the monument was a decade in the making. “For years, historians assumed this kind of departure had always existed,” she said. “But our research confirms Gary was the first person to look at a kitchen full of people mid-conversation, calculate the cost of a proper farewell, and simply decline to pay it.”

Kellbrook-Ames said the Society reconstructed the moment from interviews with 14 guests, none of whom noticed Gary leaving. “Several of them still believe he’s in the bathroom,” she said.

The ceremony began at 2 p.m. with remarks from Dr. Alistair Venn-Tuttle, a senior fellow in Threshold Studies at the Northern Midlands Institute for the Study of Doorways. Venn-Tuttle described the Irish goodbye as “a profound act of trust in the group’s ability to carry on without you.”

“Gary understood something we are only now beginning to grasp,” he said. “Nobody is keeping track of you as closely as you fear.”

Venn-Tuttle then began a long, emotional thank-you to the Society’s board, the Pruitt family, and the caterers. Attendees say it was around this point that the crowd began to thin.

“Gary understood something we are only now beginning to grasp. Nobody is keeping track of you as closely as you fear.”

By 2:45 p.m., according to the Society’s own account, roughly a third of the audience had slipped out. Kellbrook-Ames noticed the empty chairs during the unveiling, which she conducted herself, and pulled the cloth from the plaque with what she called “a feeling of mounting solitude.”

By the time the ribbon was cut, she said, only the plaque and a visibly moved Venn-Tuttle remained. Venn-Tuttle was last seen fixing himself a plate of cheese cubes. He has not been located since.

Society officials said they cannot say when the ceremony officially ended. Kellbrook-Ames recalled finishing her remarks, looking up, and finding the folding chairs empty. A volunteer was said to be holding a clipboard at the back, though she was gone by the time anyone turned to ask her.

“We think the program concluded around 3:15,” Kellbrook-Ames said. “Possibly earlier. I turned to thank the volunteers and they had all, in a sense, honored the occasion.”

The plaque has since drawn visitors, though none have been seen leaving. Society staff say they have stopped trying to count them.

Gary, now 71, could not be reached for comment. His daughter said he was informed of the honor by phone but hung up before she could finish the sentence.
