Angela is upset that Robert cannot give her a bigger part in the television episode. She vents.
Angela: WHY can’t I wear the red dress?
Robert: Your part is the bad girl. Black is symbolic.
Angela: I don’t always want to play the bad girl. Sometimes I want to play the good girl.
Robert: The character becomes you.
Robert: You know…
Angela: You think I can’t do GOOD? THAT ticks me off.
Robert: No need to get angry.
Angela: I’m not ANGRY! I’m just a little CROSS, PEEVED, IRKED. All right so, I’m LIVID.
There’s a lot of words for angry. Ranging from "indignant" to "wrathful," from "fly off the handle" to "go ballistic." Colorful.
