The afternoon on December 25 in the waiting room, I was the nurse on duty. When I felt sad about having to 1 on Christmas Day, a woman and four small children showed up at my desk. “Are you all sick?” I asked. “Yes.” the woman said 2 and lowered her head. But when it came to telling me about their 3 , things got a little surprising. They all seemed to be well and there was nothing 4 with their body. Why did they tell a 5 that they were all sick? I did not say anything but 6 that it might be a little time before a doctor could 7 them . The mother said, “Take your time. We can 8 here. It’s so warm.” When she finished the register chart, I noticed she didn’t write down their address----were they 9 ? I looked at the 10 around the Christmas tree. The children were excited and 11 to be healthy. The littlest one was pointing at the Christmas tree and said something to the mother. Then I was sure that they came here not because of 12 but only for warmth. I went back to the nurses’ station and 13 the homeless family. The nurses, 14 about working on Christmas Day like me, turned to feel sorry for the family and decided to 15 .We bought delicious food in the hospital restaurant and 16 a big dinner for our guests. We needed 17 . So we put apples in a basket and collected candies and clothes. Just as we were seriously prepared to meet the physical needs of the 18 , our team worked to meet the needs of a family who just wanted to be 19 on Christmas Day. Later, as the family was to 20 , the youngest child ran to me and said, “Thank you very much. Good bye. ”
