Leila is the protagonist of the story 'her first ball'
She is shown very excited and enthusiastic at the start of the story as it is was her first time ever going to a ball. She was so excited that she wanted to tell everyone about it. She was naive and decent. Since she was skilled in dancing nobody could tell that it was her first ball.She was touchy as she reacted on the old man's story. Because of her innocent and sensitive nature, the fat old man succeded in brain washing her. Due to this, Leila had her mood swings. The feeling of nervousness, excitement, enthusiasm and happiness changed into sadness and confusion. But when she was offered to dance again by a young man, her mood changed back to happiness and enthusiasm and she forgot about what the old man told her.
A young girl called Leila has come to the city to stay with her cousins, the Sheridans (who also appear in "The Garden Party.") As the story opens, they are going to a ball. Leila is very excited: this is her first ball. Once there, she is both excited and terrified. After dancing with several young men, she dances with an old balding man who has been coming to balls for 30 years. He tells her that she will eventually grow old and only watch the dances, regretting her lost youth and beauty. For a moment, the magic of the occasion is spoilt. Then another young man asks Leila to dance, and her worries disappear.
