when i studied in highschool, I often back home late because my school is so far from my home.It take me three hours to get home and I also like to find something to eat before back home. When it's night,It's so dark and quiet . I used to meet a madman on the way home. At that time,I was waiting the bus with my friend. That madman came to me and wanted me to give money to him. Then I refused him and standed behind my friend. I think it so funny but also danger.
