Monologue help!!!!!!!??

I have to audition in 2 weeks. I have a song but no monologue! (If it matters, my song is "Think of Me" from the Phantom of the Opera) Does anyone know any good monologues for 13 year old girls? (I included this because my theatre is adamant about auditioning with age-appropriate monologues.) I usually do funny monologues but I would not be opposed to something more serious. Thanks in advance!
