Introverts are not hermits. Introverts still live and interact with and within that society. There is a difference between typical day to day social relationships and deep relationships (as with a spouse/best friend/etc.) Introverts may hate the first, but I know few introverts who do not participate in the second in some way (even online as we are now doing.) People are naturally social, it's just a different type of social when discussing introverts versus extroverts. Again, don't confuse introvert with hermits.
