The kind of brain-washing it do to which an add on is the that it gets over filled with negativity.
Personal observations :- people actually don't know what they are saying and why the hell they are saying during *anger performance*
Anger can only distant people.....and once gone.....its really hard to re-create that love that balance.
Stay calm. Say thing.....make your point....give justification(if required) but don't shout. I know its hard (personal experience) but it can actually save lot of hearts from breaking.
Sighhh.... God bless them who actually do this deliberately to impose themselves. Because, only God can help them.
