When is your birthday?
August 1st.
Do you usually have a birthday party?
Yes, we do. My parents prepare dinner for me.
What would you do at the party?
We sing' Happy Birthday' at the party and have birthday cakes.
Do you know when people began to sing the song'Happy Birthday'?
Well, I don't know.
Let me tell you the story. In 1892, Patty Smith Hill and Mildred Hill wrote a song called' Good Morning to you'. But later someone added the words 'Happy Birthday' to their tune.
So the 'Happy Birthday' song has been popular since then?
