what constitutes a good conversation?

Throughout the day, we have many different conversations with people. But how many of them are actually good conversation? I think a good conversation is one where everyone involved is able to listen and feel free to ask questions or disagree; where not everyone has to have the same opinion. A good conversation influences the thoughts of the participants, even after the conversation is over, encouraging them to reflect on it and let it impact the rest of their day because it was that meaningful or interesting. People should be open minded and willing to accept new ideas, instead of insisting that only their own are right. On the other hand, people should not be afraid to speak up and voice their own opinions. The best way for a conversation to be good is to have different opinions and ideas come out into the open and be able to float around for others to hear out, whether it's to agree or disagree.
