Quote from : My Sister's Keeper Book

There should be a statute of limitation on grief. A rulebook that says it is all right to wake up crying, but only for a month. That after 42 days you will no longer turn with your heart racing, certain you have heard her call out your name. That there will be no fine imposed if you feel the need to clean out her desk; take down her artwork from the refrigerator; turn over a school portrait as you pass - if only because it cuts you fresh again to see it. That it's okay to measure the time she has been gone, the way we once measured her birthdays.
