"The rest of the family is home, where it's__1__."
     Just another one of his__2__ideas-a big tamale (玉米粉蒸肉) feast after tonight's Christmas Eve
service at the church-and look where it landed him:waiting in a line 50 people deep.
     Who would have guessed that the tamale in every shop in the city would be sold out the day before
Christmas?But they__3__, as Carl knew.He had been driving all over El Paso that morning.__4__to bring
home tamales, Carl tried one last shop, an old favorite out in Canutillo.

     "I'll get your order of tamales and bring them to your house."
     Carl's brow furrowed "I couldn't ask you to do that."
     "But it's__19__I can do.You lent me your coat." Her smile overrode (推翻) his objections."Just give
me your address." She and her little girl settled in for the long wait.
     And at__20__noon on Christmas Eve, they delivered four dozen fragrant tamales-along with Carl's
brown jacket-to his home.
