In Bowling Alone, Robert D. Putnam writes:

Before October 29, 1997, John Lambert and Andy Boschma knew each other only through their local bowling league at the Ypsi-Arbor Lanes in Ypsilanti, Michigan. Lambert, a 64-year-old retired employee of the University of Michigan Hospital, had been on a kidney transplant waiting list for three years, when Boschma, a 33-year-old accountant, learned casually of Lambert's need and unexpectedly offered to donate one of his own kidneys.

"Andy saw something in me that others didn't," remembers Lambert. "When we were in the hospital, Andy said to me, 'John, I really like you and have a lot of respect for you. I wouldn't hesitate to do this all over again.' I got choked up." Boschma returned the feeling: "I obviously feel a kinship [with Lambert]. I cared about him before, but now I'm really rooting for him." This moving story speaks for itself, but the photograph that accompanied this report in the Ann Arbor News reveals that in addition to their differences in profession and generation, Boschma is white and Lambert is African American. That they bowled together made all the difference.
