Maybe he has his own reasons. It could be that he doesn't agree with her idea or doesn't want to do what she asks.
It could be that she's communicating to express her feelings or to give information. Maybe she's excited or worried about something and wants to let it out.
Maybe she's had a bad experience that made her like that.
It could be that she didn't get what she wanted or was treated unfairly. Sometimes, cartoons show emotions without giving a specific reason right away.
