    My wife and I were at a crowded grocery store not long ago. It was a weekday evening, cold and wet-and tense. People were carelessly blocking aisles, complaining and cutting one another off with their carts.

Things got worse at the checkout line. The cashier scanned a man’s discount card, but he misread the savings on her screen as an additional charge. He decided she was acting deliberately and began to argue.

“She is being spiteful (恶意的) !” he yelled. “This is unbelievable.”

Other customers looked away as the cashier tried to reason with him. She called a manager, who accompanied him to customer service. Shaken, she moved to the next customer in line.

We’ve all witnessed uncomfortable scenes like this in public places. The grocery scene was another example of how our trust in others has eroded. But it was also a teachable moment on how we can rebuild our faith-starting with just one person.

Back at the grocery store, my wife and I reached our uneasy cashier. I grabbed a bottle of water from a nearby cooler and handed it to her. “We felt bad about how that man treated you and wanted to buy this for you.” I said. Her face lit up, and we talked as she scanned our items. She told us she had been working that evening through severe foot pain and would be having surgery later that week. We wished her well in her recovery, and she thanked us as we left.

Those are the balancing acts, the moments of responding social and emotional pain with healing, which will add up to restore trust among people. You can start that pattern in someone else’s life, even in a place as ordinary as the neighborhood grocery store.
