Question

When people who know each other fight, what has usually happened?

Answer 1

It is the last one. A series of events has to lead up to the fight.

Answer 2

Honestly all of those could be a reason for a fight. sometimes people want ti just pick fights for no reason. others pretend to be angry because their friend is angry and they just want attention. in other cases one event could cause a huge fight like spilling your bffs secrets or getting others to turn against your bff. the most common is a leading series of events that can cause a fight. actions may have hurt others who were holding in how the felt until just snapping one day. so honestly the last on emakes the most sense
