I voted "no"- I'm not a fighter.
But, about 17 years ago, when I had been out of college a couple of years, my best friend was dating a real jerk. DH (then DBF) and I went out to a local watering hole with them, and he had way too much to drink and started verbally abusing my friend. I told the jerk to chill out- well, he didn't like that too much. He ran right at me, and pushed me hard into a waitress. We both fell down- the bar called the police. I had a big lump on my head, and so did the poor waitress. We were asked to leave, and the police let us go home without anyone being arrested (jerk was the only one drunk). Thinking back on it now, I should have pressed charges. The worst thing? My friend actually married the jerk a few years later- only lasted 3 years, thank goodness.
Technically, it wasn't a fight, since the term implies both people involved actually hitting each other. I did no hitting- I just got hit.
