The story from the girl: "I go in a trolley bus. In front of me sits an elderly couple, a man and a woman aged 60. A woman looks at something in her smartphone. A man looks at everything around. Suddenly he smells, looks at me and asks, “What does it smell so delicious in a beautiful stranger’s bag?” I said, “The butterflies. Go to my friend.” He said, “Couldn’t we be friends?” The woman, looking away from the smartphone: “No, you’re already friends with me.”
