Arguments vs. Fights

I always thought arguments and fights were the same thing - there's a disagreement, there's a quarrel, someone ends up eventual "losing" whether by words or by fists. However, today I learned there is a fine difference between them after looking through "Thank You For Arguing" in class. Within the book, I learned how to utilize rhetoric to persuade someone, how fights differ from arguing, and how to seduce your partner with roleplay. You know, typical class things!
