Quick Definition: Assuming that you knew the person for a long time and treating them like a good friend.
One of the great ways to make friends is to assume familiarity. Even if the other person does not respond, you can go in another direction. Most of the time, it allows you to make friends quickly, and have social fluidity in any situation. Dale Carnegie takes this concept further by saying, never argue directly with people, and always ask them to talk about themselves. People tend to like to focus on what they are working on, instead of being interested in other people first.
This technique works if an artist is overly nervous when talking to a girl he doesn’t know. Sometimes, the right in-field instruction is, “imagine she’s your sister” or imagine that person is just a friend you’ve known for a long time. This takes the pressure off of actually “getting something” and just being able to vibe in a friendly way. The same way you hangout with another friend.
Usage: Assume familiarity with all the girls you meet.
