Both, but secara keseluruhan, keseluruhan I think Cathy is the most rude. She eats pizza at the Joffrey audition and won't be quiet, she copies Abby's routine, she refuses to be part of the team (when Vivi danced with the ALDC), and she humiliates Chloe!
They are both really bad people but Cathy colts Abby She tryst to bring down the KIDS FOR GOD SAKE!!!!LEAVE THE KIDS ALONE I'M 20 years oldI played the part for Luna in HARRY POTTER!!!!!And if anda don't STOP I WILL GO TO PITTSBURGH and SEW anda CATHY
Well I think there are two different ways anda could look at this...
Cathy is incredibly snotty the way she treats everybody else and the ways she acts. Especially when add tried to sneak that older girl into Brooke's age division just so she can beat her. So yes, Cathy is a very rude person.
One the other hand, Abby is also rude. She screams at the mothers when their daughters cry. It's just what mothers are supposed to do, help their child! Although anda can't really blame Abby for that considering she has no kids and doesn't know what it's like to be a mom...
Anyways I guess anda could say both Cathy and Abby are rude. I hope anda like my answer!
Cathy, because Cathy can be really rude and annoying and she just pretends 2 be nice 2 girls 2 give Abby a bad reputation! Plus she is mean 2 OTHER dance studio's moms and makes them feel bad soo, Cathy.... Defiantly Cathy
