My child is yet a stranger in the world - Romeo and Juliet

My child is yet a stranger in the world;
She hath not seen the change of fourteen years.

– William Shakespeare

Romeo and Juliet, Act 1, Scene 2. Old Capulet shows himself to be a protective father when Paris asks about his daughter Juliet’s hand in marriage. Capulet points out that she "hath not seen the change of fourteen years" and uses the metaphor of "stranger in the world" to emphasize her inexperience.
