Write a concluding sentence.
You can be a good conversationist by being a good listener. Firstly, when you are conversing with someone, pay close attention to the speakers' words while looking at his or her face. Show your interest by smiling and/or nodding. Furthermore, don't interrupt when someone is speaking; it is impolite to do so. If you have a good story, wait until the other is finished. Also, watch your body language; it can affect your communication whether you are the speaker or the listener. For instance, don't sit slumped in a chair or make nervous hand and foot movements. Be relaxed and bend your body slightly forward to show interest in the person and the conversation.
