It annoyed me in FFVIII when Rinoa pushed Irvine down the stairs in that prison place, and then said she 'scratched' him or something to get him to do something for her. That made her sound really catty and bitchy, which she's not.

Also, in FFVII, when Aeris, Cait Sith, Cloud and Tifa are all in the Temple of the Ancients and Aeris asks Cait to read her and Cloud's compatibility. Cait says something like "Oh, poor Tifa" and Aeris' reply is "Let me see! I don't mind!" whilst Tifa is visibilly distressed (well, she puts her hands on her hips) This made her seem bitchy too, which is completely un-Aeris.
