Daughter:
Dad, congratulations on your childhood!
It is a happy thing for a girl to have menstruation. Because this means that you have grown into a big girl, you will have a beautiful life and future, and your appearance, language and heart will be more perfect. When you mature day by day, you will be more sensible and have the courage to face the difficulties that may arise on the road of life. Of course, you will also know how to study hard to win a more precious life.
Dad watched you grow up day by day and become an ideal, knowledgeable and promising child. I believe that my daughter will be better than my parents in the future. Dad bless you!
Maybe you will have more heartfelt words, then say it to your mother or to your father.
Love your father
