This video has it all, violence, profanity, echoes of racism in America... What shocks me is not that two people of a different race got in a fight, but that people are talking or even looking other people in the eye on a bus. Check the video:
Bull mess started, bull mess ended. That simple. When I saw that yesterday, the racial aspect is obviously the first thing that hits you. Then I rewatched the video and saw that the fight really began over a mumbling misunderstanding. That is what I tell kids all of the time, enunciate. Speak correctly. This video is a good example of why you should speak clearly. Do not be lazy with your speech or you may get your ass beat.
