Besides the dangers of getting involved, it's sometimes hard to tell whether something is a serious incident or just people fooling around. I've seen both sides of this: Guys I assumed to be friends jokingly greeting each other while in fact one was starting a serious fight and the other one was too drunk to react appropriately. At some other time, I saw a woman yelling at a man, while he was somehow holding her. Seconds later, they were laughing and walking off side by side.
