Answer: The surest way to take your turn at the right time in a conversation is to listen for pauses.
Explanation:
The most prominent rule of conversational etiquette is to respect the other person's opinion and to ensure everybody gets a chance to have a say in the argument.
The best way to respond to the other person is to listen for the pauses, where they expect you to give your stance and similarly take pauses and let them speak.
This will demonstrate that you have the respect for the other person's opinion and you are an active listener in the conversation.
