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.

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.
