I thought my mom lied to me,
When my mother used to drive a taxi, she came back and said that one day she pulled a passenger, who was a participant in the bridge. Then when the man passed the bridge, she asked my mother, do you know if Hazi should put the cow on the bridge? My mother said she didn't know. Then the man said that one day he dreamed that the bridge was going to be flooded or collapsed (sorry, I heard it from my mother in elementary school, so I remember it was not black) and invited someone.
This is the story I heard, which later proved to be true ~ I always thought my mother was angry with me.
