Imagine you are at a party with many people around you. Some you know, many you do not but would like to get introductions. You overhear a man whom you have never met talking about an interesting topic. You decide you want to get to know this stranger, even though he has not noticed you yet. You simply turn to the man, smile and say, "We should be friends." What do you think this man's reaction will be to hearing such a bold request from someone he doesn't know anything about?
