Venting or Rage!

When a parent screems angryly at his child for something they did or didn't do and then the child re-acts with screeming anger, and slamming doors, and verbal abuse (from both, parent and child), are they both venting or in rage! As... venting is an opportunity or means of escape, passage or release, outlet like (finally gave- to his pent-up hostility). and Rage is uncontrolled anger, an intense feeling; or Ragged, as worn out from stress and strain.... SO is the above behavior of parent and child from stress and strain or pent-up hostility!!! And with this kind of behavior in a childs life how does, he or she , learn the diffence!
