     My goddaughter, Shari, owns The Berry Factory in Sacramento, California, and her mother, Joan,

and I were helping with the Valentine's Day rush of 2011. We'd been preparing hundreds of berries,

arranged gift baskets and packaged orders to be shipped around the country.

     By the end of the day and I were exhausted. Shari didn't seem tired. That was what Shari liked doing

especially when she gave someone else something. I'd seen her give away berries to everybody-parking

attendants, mail carriers, hairdressers. "For me?" they'd say, breaking into a smile.

     As a "thank you", Shari took us out for dinner. But there was a 45-munite wait at her favorite

restaurant. "No big deal. There's another place just up the road," she said, driving us there. This time we

walked right in. While the waitress took our drink orders Shari reached into her handbag, pulling

something out.

     "I want you to have these," she said, handing the waitress a box of chocolate-dipped strawberries.

     "Will she love those berries!"I said to myself. But the waitress seemed extremely surprised. She hardly

let out a "Thank you" before grabbing the box and rushing into the kitchen.

     A few minutes later, the waitress returned with our iced tea. " I apologize," she said. " It's just …my

best friend and I made an agreement to send each other something every Valentine's Day. But she passed

last year. I didn't know how I'd get through this day without her. Then you handed me that box."

     "I'm so sorry to hear that," said Shari. " It's not much, but I hope you can enjoy them."

     "Oh, I will," the waitress said. " See, every year we always sent each other the same thing: a box of

chocolate-dipped strawberries bought from our favorite store, The Berry Factory.
