They do not listen & Farrah did not listen. They employ what can only be called 'playground tactics' to out shut and talk over the person they are arguing with. Its is so juvenile and immature.
Contrast their style of 'discussion' with James, Bobby, Sherrie and even Stevie, its very clear they think that shouting the loudest can win an argument. It does not, it never has and never will.
The tactic of 'Answer yes or no' may work well in a courtroom movie but in the real world don't try to limit my response to a one word answer, that's trying to put words in my mouth.
The way someone handles discussion, argument and confrontation says volumes about their maturity and respect for others. Austin and Jenna have a lot to learn but it is doubtful they will ever change.
