write two expression showing maintaining a conversation!

 1.We could be friendly : It shows that we don't have the fear to start up a conversation. It also makes them/people/ a person we are talking to think that we could start a conversation easily and also make them think that we maintain materials easy.

2. Speak polite, and watch your manners :
Our politeness, and our manners effect who we're talking with. If we don't talk at  the middle of the conversation, who we're talking with will think that we are listening very well and not ignoring what they are saying.
