Often we listen with intent to reply, i also often do this, as my friends or other person speak instantly inside my head i think about a reply. This is bad habit, not only i am not understand what the person in front of me saying, often i repeat what they say because iam not listening, i am thinking. Maybe the reason why we have two ears and one mouth is so we listen more than talk. :)
Now iam trying to really listen, and it have good impact, my reply more quality, sharp and effective cause i am not repeating the sentences like parrot :D, usually people repeat the sentence when they cant understand or mostly they dont listen.
