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?
