Why is it that certain people I know IRL have to keep talking after an argument is over?

The people who overreact to the smallest thing, leading to a spat, which settles down... then they keep ****ing talking inside the other person's hearing range as to instigate a much larger fight. Then when a real fight breaks out because they were *****ing and crying about something unrelated and ****ing retarded as all ****, they come up with "WHY ARE YOU PICKING A FIGHT WITH ME????"

What the ****? Just shut the **** up and complain to someone else where the other guy can't hear, you're just making **** worse by being a ***** about starting a fight. Argument was over five hours ago, why are you still talking **** like the other guy isn't there?

When the other guy leaves, take it as a sign of submission and shut the **** up about it. Don't be a ****tard douchebag who keeps talking smack even though they're the ones who started **** and the other guy was mature enough to not rise to the bait.
