describe the conflict between ella hattie and olive in chapter 3

Ella goes back to the funeral, and her father tells her to change into something clean for the dinner. In her usual contrary way, Ella puts on a bright green dress, inappropriate for a funeral. Her father introduces her to a woman named Dame Olga, and leaves Dame Olga's daughters to comfort Ella. Hattie and Olive are just as fat as their mother, and just as rude. The first thing they point out is the spectacle Ella made at the funeral. Although they pretend to have no appetite, Ella cannot believe the amount of food the two girls put away.
