When an extreme extravert leaves a party at two o'clock in the morning, he may well be ready to go to another one. His batteries are almost overcharged, having received so much energy from the interaction. The introvert is territorial.

Introverts avoid being the center of attention and are generally more reserved than Extraverts. The intuitive finds appeal in the metaphor and enjoys vivid imagery.
