Self-Introduction Before the Hospital Bed

She suffers from Alzheimer's disease and doesn't recognize him every day. He introduced himself again every day: "Hello, I am your husband." She smiled and stretched out her hand: "Hello, please take care of me." After five years of this, he collapsed from exhaustion and was hospitalized. She suddenly woke up one day, walked to the hospital bed and said, "Why are you so old?" He was stunned. She held his hand and said, "I get lost in time every day, but I know that you have been waiting for me at the end." That night, she fell asleep quietly next to him and never woke up again. He held her hand and said, "This time, I will wait for you."
