Read the lines from Act I, Scene v of Romeo and Juliet.

Romeo: [To JULIET.] If I profane with my unworthiest hand
This holy shrine, the gentle sin is this;
My lips, two blushing pilgrims, ready stand
To smooth that rough touch with a tender kiss.

Juliet: Good pilgrim, you do wrong your hand too much,
Which mannerly devotion shows in this;
For saints have hands that pilgrims' hands do touch,
And palm to palm is holy palmers' kiss.
