At 95 years old

my mother passed away in the early hours today. Her own mother got to be 100 years old, and I had begun to think that my mom would match that, but now it was her time to go. I stayed with her the last 24 hours or so, but fell asleep for two hours in the middle of the night and she used that "window of opportunity" to pass away. It's probably always sad to lose one's mother, but I feel that it's a little bit different when people are old and weary. She also had Alzheimers, so the last years it's been more and more difficult to communicate with her. But she recognised us almost to the end, and I'm very grateful for that.
