In truth she was a very bitter woman, bitter that as a child every action she ever took, every achievement she ever made was always held up against her sister, Lilly. When Petunia did well in a test it didn't matter because Lilly had done well in her freak school. When Petunia fell in love with Vernon it didn't matter because Lilly had fallen in love with the wonderful, perfect James. When Petunia had lost her mother and father it didn't matter because Lilly was in danger and finally Lilly had gone and gotten herself killed but that didn't matter, even with her dead Petunia could never ever escape the shadow of her perfect little sister, The magical child, the special one, the perfect one.
