To this day I thank my lucky stars that I didn't get killed, but.....
I was living in a less than high quality neighborhood when I saw several bikers and their ladies hanging around a nearby bar. Just as I was walking by on my way home from work, things got testy between one of the bikers and his lady. He called her several really awful names and shoved her hard. I can't imagine what got into me, but I marched up to him and read him the riot act...told him that he was the type of biker who gave bikers bad names, and that if his lady was really all those awful things he called her, that he had terrible taste in women. I turned to her and said I didn't believe a word he had said about her, and that she deserved better. Amazingly, the other biker guys told him to lay off his lady and told me she would be okay, that they would keep an eye on the situation. This is not something I would encourage anyone else to do!
