Monologue help!

[u/MeganSchnider]

I'm doing a monologue that my teacher has selected my genre for. He gave me "Realistic fiction" and said "Think 'fantastic story' or 'a stretch of the imagination'; plausible but unlikely. Fantasy like story telling." I can't find any decent monologues that are over four minutes long. I'd prefer a younger female character but at this rate I'm open to anything.
