On the stage you share your joy and your capability
You know not who’ll be moved by your sincerity
Believe in yourself as a paragon of talent and moral quality
Be bold enough to show the world your versatility
You may not believe someday a famous star you’ll be
Time flies and you review your episodes of life retrospectively
Friends and kinsfolk will help to compile a memoir of your life in futurity
As a friend, neither could I sum up your past nor your future I foresee
But on this big day, I can wish you a Happy Birthday and eternal felicity.
