Introverts are Irresistibly Attractive

Introverts may have a smaller network of friends, but they tend to be closer to those friends that they have – think quality versus quantity. Because of this more-solidified bonding, they are loyal, and often times, put others before themselves. They may enjoy two player board games to larger group games, because they cherish deep rather than shallow interactions.
They believe in you, are your biggest cheerleader, push you to excel, and wholeheartedly trust you. They will stick up for you until the bitter end. They are your most trusted partner-in-crime and your confidante.
