To surprise your important person's birthday,
at first, you pretend to forget his birthday.
If he asks what date today is, you just answer normally.
Try not to be exciting, it's just a normal day.
If you do this, he will think you forget his birthday.
When he is alone, you sing Happy Birthday Song and appear with cake.
He will know that he was surprised on his birthday.
