Improving Relationships

Yesterday I was quite amazed the way our chat session proceeded. No arguements, comments, interceptical talks. I expressed myself clearly and acknowledged properly from that side. So I'd like to draw some guidelines for a proper chat as follows:

1. Speak less and listen more and more.
2. Acknowledge constantly rather than maintaining the silence.
3. Unless if someone ask your opinion, don't open out volunteerily.
4. Make sure your mike, speakers are functioning properly.

Did I missed any other valid points..?
