Mum went to Peter’s bed and said, “I want to borrow Tim’s radio for you.” Peter touched the letter in his pocket and said, “Thanks, Mum ! But you are so tired now.” “Today I want to send you a special gift on the radio. It will surprise you. I will come back soon.” Mum said and quickly left in the heavy snow.

Peter took out the letter. He got it in the afternoon. Mum didn’t know about it. Mum wrote in the letter: The 26th of this month is my son Peter’s birthday. Could you please bless(祝福)him on Happy Family? He has been ill for one month. The radio station wrote on the top: I’m sorry to tell you that we have canceled(取消) this program.

Mum came back with a radio. She walked very slowly. There were lots of snow on her clothes. And the program began quickly.

Next Peter got very surprised. “Originally(原来),we planned to cancel this program, but lots of people like it very much. Now, let’s bless the following people together, Kate, Martin, Linda...”The list was long. Mum was too tired and she fell asleep. Peter didn’t hear his name to the end. But he was quite moved(被感动). He woke up Mum, “Mum, I heard my name just now. They said I am a very good boy. I am very happy. Thank you for your nice birthday gift, Mum!” Mum smiled with tears. Peter also smiled with tears. He believed it was the best birthday gift for him.
