When approaching a group of people who are engaged in conversation, it is important to evaluate the situation before interrupting the conversation.
1. Read the body language. If people have their heads together and appear to be in a serious conversation, it might be better to find another group to speak with at that time.
2. Listen. Remain silent until you fully understand what the discussion is about.
3. When you do speak, be sure your comments are relevant to the conversation. Otherwise, your interruption will appear rude.
