Julian Barnes, one of my favorite writers. Barnes has a book called Levels of Life.
When Barnes lost his wife and companion, the love of his life, he wrote this book to deal with his grief. They had been married for thirty years and in love for that duration. The loss of his wife, journalist Pat Kavanagh was, of course, traumatic. The book deals with love, loss, and grief. Throughout the chapters, Barnes attempts to make sense of the grieving process. Here is one of the most striking excerpts:
“This may not be mathematically possible; but it is emotionally possible.”
