My dear wife Tammy passed away in her sleep early Saturday, October 19. When I awoke at around 6 a.m., it was clear she had been gone for several hours. It came as a shock. I couldn’t believe I hadn’t been awakened somehow, but all indications are that her spirit simply slipped away during the night. Her face looked serene, with her eyes closed and a slight smile. It was devastating to discover her that way, but I’m so grateful that her death was peaceful.
