What arguments did Laura use to convince her mother Mrs. Sheridin in the story “The Garden Party”?

Although she did not know the Scott family well, if at all, Laura was deeply upset by the news. She told Jose they had to call the party off. Jose told her that she was being stupid and that no one would expect them to cancel the garden party just because Mr. Scott died. Laura tried to appeal to her mother but Mrs. Sheridan was of the same mind as Jose. To distract her daughter, Mrs. Sheridan put a new black velvet hat with a yellow daisy trim on Laura’s head but it was no use. Laura stomped off into her own room and shut the door.
