DUNCAN, Okla. —
"It was hard," Hanson said of raising such a large family. "You missed a day and you got behind.
As they raised their family, Hanson joined the oilfield, where he worked for several years before retiring.
However, retirement didn't mean a lack of work. The Hansons owned and operated a lawnmower store and service for many more years after Hanson left the oilfield.
Through it all, the twins stayed close. Thelma said she recognized a strong bond in the siblings when she first met Anderson.
"They were always having something together," she said.
Hanson and Anderson were more than emotionally close for a short time in the 1970s, when they were neighbors in Loco.
No matter their age or the distance between them, the Hanson twins have a bond they don't intend on breaking.
"We always try to see each other," said Hanson.
In between visits, the siblings keep active by doing things they love. In fact, Anderson plays pool three times a week.
