"Well, we have baskets, 3 they're not East baskets for kids; they're food baskets," I explained. That morning I had arrived at St. Michael's Church in Carmichael, California, to help 4 the baskets to needy families for Easter. To make sure the needy would 5 the offer, we had handed out numbers to them 6 matched the basket they were supposed to receive. Each one contained a full Easter dinner-a whole ham, potatoes, bread, vegetables and a pie- enough food to help 7 a family for a week. "Why don't you come in?" I said to the man. He looked 8 .

"Happy Easter," I said to the man, handing him the only food basket with an Easter basket inside-the very same basket with his number on it. "Someone already knew just 20 you need." | ||||
