In my opinion, people that 
talk talk talk times 100 are not neccesarily people that know what they want.  They could be talking for serveral reasons:
 

 bored
 

 distraction from what's really on their mind
 

 selfish
 

 don't like quietness
 

 like to gossip
 

 don't care to listen to anyone else
 

 feel that their opinions are more important than anyone elses
 

 stubborn
 

 feel that their feelings are valid than everyone elses
There are many reasons for someone to talk excessively.  I know it's an ambigous subject.  However, I want to find out what people think so next time someone is talking excessively I don't say the wrong thing to hurt their feelings or say something I might regret.
