Where can I find dialogue from the play Romeo and Juliet between two characters from the play, at least 20 lines long?This is for drama class

The first one I would consider, which is simply 4-5 lines
each back and forth would be the last 20 lines or so of Act I, scene 2.  It's between
Romeo and Benvolio and they are discussing crashing the Capulet party where Romeo can
compare Rosaline's beauty to others at the party.

The next
is Act II, scene 2, where Juliet starts with the famous "Romeo, Romeo, wherefore art
thou Romeo" line. They go back and forth through the famous balcony scene, and it would
be fun to do as well.

Another scene that would be fun would
be the bantering back and forth between Mercutio and Benvolio in the very beginning of
Act II, scene 4.  Neither one knows that Romeo is now in love with Juliet, and both are
worried about Tybalt's challenge to Romeo.  This would be good since they go quickly
back and forth as well--and Mercutio is always a fun character to
portray. 

Hope that helps!  Good
luck!
