Imagine you walk into a party. You know the host, and you've become quite close but know none of their friends. It is the first time to meet them, and you want to impress! You walk in and get a drink. You can't see the host, so you are standing alone. Someone approaches you, and you begin to chat. The person asks you about yourself, how you know the host and what you do. You speak about yourself, quite comfortable in this conversation. Yet. the person quickly moves away to another group. They don't invite you to meet others. Why?
