Not knowing we were poor, my kids just thought I was 3 . I've always been glad about that. It was Christmas time, and although there wasn't 4 for a lot of gifts, we planned to celebrate with a family party, but the big 5 for the kids was the fun of Christmas 6 .

"I was looking 16 thinking of what to buy, and I 17 to read the little cards on the 'Giving Trees'. One was for a little girl, four years old, and all she 18 for Christmas was a doll (玩具娃娃). So I took the card off the tree and 19 the doll for her. We have so much and she doesn't have anything," I never felt so 20 as I did that day. | ||||
