Paul and Sue King live in Oakland, and they have been regulars this season at Messalonskee High boys’ soccer games. They especially love watching their grandson, Chris Hall, who scored the winning goal when the Eagles defeated Hampden Academy on Wednesday in the Eastern Class A final.

But when Hall and his teammates take on Windham for the Class A state title at 5:30 p.m. Saturday at Falmouth High, Paul and Sue are clear: They will absolutely not be rooting for Messalonskee. They just can’t.

It’s not because of some ugly family incident. It’s simply a matter of being unable to choose between their two grandsons. Hall’s cousin, Dana King, is also Paul and Sue’s grandson, and he happens to be Windham’s goalkeeper.

“I want both of them to win, but I know that’s not possible,” Sue said. “I love both of those boys. I’ll be happy for the one that wins, and so sad for the one that doesn’t.”

Hall and King are nine months apart in age, so they had common interests as kids, including soccer.

“We’ve known each other forever,” Hall said. “I’ve probably known him since I was 2. We’ve always been close.”

They played together on travel soccer teams, but the last time they played against each other in a competitive setting was about five years ago, when Hall’s U-13 Waterville Novas played a friendly game against King’s U-12 team from Windham. Who won that game is not in Hall’s memory bank.

“I honestly can’t remember,” he said. “I know it was a close game.”

“I’m pretty sure we beat them, but I’m not 100 percent sure,” King said. “I’m 90 percent sure.”

Hall is a center back who has scored 12 goals this fall. He sometimes warms up King before Windham games. He did that on Oct. 1 when, in a preview of the Western Maine final, Windham knocked off Scarborough, 3-2.

Hall stuck around to watch some of Windham’s games, so he has a decent scouting report. King, meanwhile, hasn’t been to a Messalonskee game this year.

“It’s a little unfortunate, because Chris has gotten to see us play,” King said. “So it’s a little bit of an advantage, but it’s all right.”

Messalonskee was the sixth seed entering the Eastern Class A tournament, but won the regional title by beating No. 3 Mt. Ararat, No. 2 Bangor and No. 4 Hampden. As both teams kept winning in the playoffs, Hall and King started talking about possibly meeting for the state title.

“I’d send him Facebook messages saying, ‘It’d be pretty sick if we saw each other in states,’ ” Hall said.

Just before the regional finals, Hall was confident that Messalonskee could knock off Hampden, so he sent another message to King. This one said, “We’d better be seeing you on Saturday, November 5th.”

Come Saturday, the grandparents will be rooting hard for both boys, but to do so, they realize they’ll have to be a safe distance away from the fans of both teams.

“I am going to be by myself someplace. I’m sure my wife will too,” Paul said. “How do you choose? You can’t, and you shouldn’t. I almost don’t want to go, but of course I will.”

“I’m going to say, ‘Go Eagles!’ ” Sue said. “Both teams are the Eagles, so I’m all set.”
