Grandma said that there are no ghosts in this world, only people who can't let go.
Until I delivered takeout late at night and knocked on that door.
Standing behind the door was the old landlady who had been dead for seven days. She asked me: "Young man, has the takeaway my grandson ordered for me been delivered?"
I lowered my head and glanced at the order notes: The chicken drumsticks wrapped in paper for my grandma should be served hot.
At that moment, I opened the leather notebook left by my grandmother.
