She is incredibly patient.

Yeah, if it would have been me, I would have already yelled at Lady Tremaine or the stepsisters to leave me alone.

Yeah I think she puts up with a lot not to be . (:

locked in a tower with no way out??? ahhhhh!!!!!

Though Cinderella has a lot of patience, Rapunzel was locked, in a tower, for 18 years, with just a chameleon and Gothel for company. Also, she's a hyperactive person (doing a tower's worth of chores in 15 minutes IS hyperactive) so doing the same thing over, and over, and over, and over (x's by however many times 18 years worth of days is) would require a heck of a lot of patience!

or cinderella

By far.

@SnowSpirit agree

As well as Rapunzel. Maybe Snow White for waiting for her prince to come? I don't know.

I think she had incredible patience with the Beast. Also Cinderella.

I think Cinderella deserves a medal for how often she has to hear those irritating bells and demanding screeches of "CINDERELLA!" without ever snapping or losing her temper.
