An ISTJ that I've described on the forums before, who, if not cajoled with the promise of free something or other, will literally spend his entire time between his bed, his kitchen and his TV armchair. And since I'm the only one who bothers with him at all, and there's only so much cajoling I can be bothered to do since I get little out of it but a one man plague of locusts in my appartment that eats me out of house and home and gives nothing back... well, he let's say he spends an AWFUL lot of time alone. And seems to have no intention of changing this at all.

"When it all comes down to dust
I will kill you if I must
I will help you if I can" - Leonard Cohen
I can't think of one in particular, but I view the extreme introverts as the people who avoid going out in public at all costs. I've known a few. They seem much more content to stay home alone all day, every day. I'm introverted but I like feeling connected with the rest of the world. So I need to get out after being cooped up for too long and when inside I like to be next to a window, especially if it's open.
My close friend has to be the most introverted person I know. She couldn't even hold a job due to her issues with being around people. She rarely goes anywhere, and if she does it has to be to someone's house with no more than two other people. She doesn't go to stores, school, or anyplace where she wouldn't know anyone else.
She's going to get tested for social anxiety.
Another close friend is similar to above situation. Except, she has Asperger syndrome. It's a shame they're both not able to go to school for their interests, as they're exceptionally bright.
He works at a job where he only interacts with a handfull of other people (federal employee) and has no public contact. Even then, he really doesn't like any of his coworkers and they don't socialize at all. I can't think of one person that he would call a friend. When family comes over for holidays or whatever, he spends most of his time watching sports on tv so he doesn't have to interact with anyone. If he knows my mom might be visiting for the day he leaves the house, usually to a casino. I have never known him to start a conversation with me. His hobbies are watching sports on tv, collecting baseball and basketball cards (which he does on-line), and going to a casino with his dad. He is one those people that answers questions with the least amount of words possible. Even my introverted husband finds him pretty hard core introverted.
His entire family is this way. His sister may be worse than he is. She lived at home with her parents until she was 26. Then she bought their house from them and they were the ones to move out. She works at a doctor's office, but she has never dated, never been kissed, and hasn't had any friends since high school that I've heard about.
And his dad, OMG! He was a night janitor at a grade school his entire life. After his wife divorced him, he never got involved with anyone again. His sister checks on him periodically because he'll go weeks without talking to anyone in his family. I've met him a few times and he is the crazy looking guy that you warn your children about. My brother-in-law is a nice guy - his dad is nuts.
My sister is very extroverted and my brother-in-law pursued her intensely. I think that is the only extroverted thing he's ever done. For all of his introvertedness, he has really grounded my sister and helped to keep her from spinning out of control. He really loves her and she loves him.
I really like him, however and encouraged my sister to date him. My sister tells me that I am her only sibling that he likes.
Social anxiety/phobia is not the same as introversion.
IRL, the most introverted person I know (who doesn't have any social anxiety) was a guy I used to sit next to at work. He was even quieter than me and almost never initiated conversations with anyone for fun until he'd got to know people a bit. His favourite holiday was to go on solitary camping hikes for up to a month at a time by himself with no contact with anyone or the outside world. He loved his dogs but didn't seem to have a close connection with anyone outside of work, and seemed happy that that's the way things were.
^^ I agree with bluebell. I generally long to be around people like bluebell described the most, but unfortunately, I think I overwhelm them with my clinginess and affection and I'm trying to figure out what to do about that without changing myself.
