As a single parent of four children, money was always tight .It was Christmas time, and although  there wasn’t money for a lot of gifts, we planned to celebrate with a family party . But the big excitement for the kids was the fun of Christmas (36).
They planned weeks ahead of time , asking (37) what they wanted for Christmas. luckily, I have saved $120 for (38) to share by all five of us .
The big (39) arrived. I gave each kid a twenty-dollar bill and (40) them to look for gifts of about four dollars each. Then everyone scattered(散开). We had two hours to shop. Then we would (41) back at the “Santa’s Workshop.”
Driving home, everyone was in high Christmas spirits (42) my younger daughter, Tina, who was unusual (43). She had only one small, flat bag with a few candies—fifty-cent candies! I was so angry, but I didn’t say anything (44) we got home. I called her into my bedroom and closed the door，(45) to be angry again. This is what he told me:
“ I was looking (46) thinking of what to buy , and I (47) to read the title cards on the ‘Giving Trees.’ One was for a little girl, four years old. And all she (48) for Christmas was a doll .So I took the card off the tree and (49) the doll for her. We have so much and she doesn’t have anything.”
I never felt so (50) as I did that day.
