I can not seem to find the quote about Pecola's mom saying that she was ugly when she was a baby. Does anyone know where that quote is?

You can find this in the section called, "Spring" and it is in the second chapter of Spring.  This section deals with Pauline and her childhood, falling in love with Cholly and having the children.  In my book, it is in a section which is italized and starts off, "The onliest time I be happy..." and ends with her saying, "Head full of pretty hair, but Lord she was ugly." I have the Vintage copy of the book and it is on page 98.
