Not quite eighteen

The three older children remembered their own mamma pretty well; to the babies, she was only a name. Janet, the eldest, recollected her best of all, and the idea of somebody coming to take her place did not please her at all. This was not from a sense of jealousy for the mother who was gone, but rather from a jealousy for herself; for since Mrs. Keene's death, three years before, Janet had done pretty much as she liked, and the idea of control and interference aroused within her, in advance, the spirit of resistance.
