Music Man and C

We are having  a little girl time tonight.  C and I are watching Music Man.  We get a few times into the movie.  And the conversation goes like this:
C:  Mom is he really a music teacher.
A:  No,  He is a con man.  He is trying to trick the town.
C: Why?
A: He is trying to trick them out of their money.
C:  He is not being a Godly man.  I don't think I should be watching this.
