Another great statement she makes is, "The biggest compliment you can pay to people you have loved and lost is to keep a part of them alive in yourself, memorializing their significance."
Though I could go on quoting her, I will stop with the most important thing I learned from her books: "Anybody who has lost someone they love has to find a new way of loving that person, since hugs and kisses are no longer an option."
How can we do this? Here is my exercise that I've learned with the help of Allison Dubois.
When you wake in the morning, acknowledge they are with you. Say their name and talk to them aloud. This is easy to do for people who talk to themselves. I am one of those.
When you partake in an activity you delight in, bring them with you simply by thinking of them as you enjoy that time. Better yet, do the things they used to love to do. My brother mows the lawn at my mom's house, one of dad's favorite pastimes. I eat salami sandwiches with asiago cheese or whatever else he used to enjoy eating, but toward the end couldn't. My mom listens to baseball games on the radio. She could care less about baseball, but dad loved the game and it is her way of saying I love you still.
These little things keep them with you. You don't have to say goodbye. Live your life to the fullest while holding them in your heart so they may continue to experience life through you.
