Fact. Introverts tend to have a more heterogeneous friendship circle. Ìt is of the understanding that Introverts lack social skills and have a lesser need for social connection. Instead what is scientificly proven is that introverts get easier overwhelmed with our generations noise culture. Introverts have a higher need for deeper connections. Which means they have lesser friends but share deeper connections. Extroverts tend to have a greater sensitivity to reward stimuli. They thrive on attention. Both introverts and Extroverts has extroverted aspirations. She just need to find out what's his interests. What makes him tick. Maybe he's and avid chess player or he want to get his pilot licence but fear she won't take him seriously. If he find someone who supports and share in his interests, he most likely will become more sociable and not so withdrawn. I am an introvert and very eccentric. I have an over analytical brain, questioning everything. My parents struggled to identify with me and eventually blatantly rejected me, expressing it openly. It wasn't a secret. Everybody knew. But you just gotta find your tribe. Then life gets so much easier. It's tough to be you if you are not allowed to be authentic.
It's weird because I have always felt I was in the middle of the two. I love my own company and being alone in general but I also have a larger friend group that I am socially active with.
