As Sister Simone Campbell, a social activist and peacemaker says, "if everyone's story is in the mix, we can resolve problems".
She means we can use a piece of everybody's perspective, no matter how quirky or off-the-wall, to help understand what happened.
In one suburban Chicago town home association in which lots of fighting had been going, conflicting stories were quietly heard by all during an annual meeting. The association treasurer, with a mediator's support, was able to express her perspective--her story about why she did things the way she did. Twice she had to suppress her tears. People were respectfully listening. No accusations. No demands. She voluntarily agreed to search for improvements with others on the board. Within days the problem of sharing bank account access had been resolved to everybody's satisfaction.
"Define the problem with everyone's story" as Sister Campbell recommends and the solution will quickly appear.
