In the days following the first anniversary  of my dad 's death, I felt sad. I still missed him so much. I would walk over to his old house where my daughter now live and still expect to see him sitting out on his front porch . I would see him in my dreams, looking young and strong again. I felt bad too because I regretted not spending more time with him while he was here. I wished I had visited him more, talked with him more, and listened to him more. I wished I had asked the questions that I never did. I wished I had given him more hugs and told him I loved him more often. I wished I had cherished the time I had with him here. I was angry at the destiny  because Dad and Mum had both passed away before I was 50, and I was angry with myself because I hadn't made the most of time I had with them. Today, I found myself walking under a cloudy sky, staring at the leafless trees. As I walked along, one of the last golden maple leaves fell from its tree and sailed in the wind until it landed in front of me. I picked it up and smiled. At the moment of peace I felt a sound in my heart and mind: "death is momentary , but love is eternal ." I knew at that moment that my relationships with Mum and Dad were not over. We would see each other again in a place of love, joy and light. We would spend our days in learning, laughter and love. What is the main idea of this passage?
