O Corin, that thou knew'st how I do love her!
I partly guess; for I have loved ere now.
No, Corin, being old thou canst not guess, (2.4.22-24)
Young Silvius assumes that, because Corin is old, he can't possibly understand what it feels like to be in love. Of course, Silvius is being silly and overly dramatic here, but this concept surfaces throughout Shakespeare's work. In Romeo and Juliet, for example, Juliet declares that her Nurse's old age prevents her from understanding the youthful urgency of her passion for Romeo:
Had she affections and warm youthful blood,
She would be as swift in motion as a ball;
My words would bandy her to my sweet love,
And his to me. (2.5.1)
