Answer 1

The reasons for this behaviour might be her disappointment.We will make her understand not to be so rude as it will create a barrier in their friendship.Her behaviour may hurt the dancers and dance teachers.we will advice her to to change the behaviour and not to be so sad because she might get another chance to represent the school if she tries to continue the dance.
We will make her be as usual as shewas and to behave properly with others.

Answer 2

She is very angry because  she wasn't able to participate in the competition. She is very sad as she alone is not able to represent the school at the group annual dance competition.She is feeling inferior to her fellow participants and she is angry with the dance teachers as they have not given chance to her.
           I would advise her not to feel sad. I would advise her to practice more dance steps so that she could get a chance next time.
