Grandma will leave soon. What can you do at the last moment of her life?
Can you cook? It doesn't matter if you can't cook. Look at the menu and try to cook a meal for grandma. Even though she may not be able to eat, can you tell a story? It doesn't matter if you can't talk. Tell grandma about your recent life. You know nothing about the people and interesting things you meet. It is also possible. Holding her hand and quietly listening to her talk about the life she had experienced, it is extremely precious for you and grandma to see one more side and spend one more minute together.
