Hello and welcome to all the new members!! Check out [agnostic.com] the introverts group if you are an introvert or you wish to interact with or better understand introverts. All are welcome! Do you have introvert tendencies?
Who doesn't like to have their own space away from everyone else? I know I like to have a bit of "me" time every once in awhile. We all have introverted and extroverted tendencies. It's part of being human. You just end up more on one side than the other. Others may go back and forth and again, that's okay. It's perfectly natural.
There are definitely people who don't need or necessarily like their own space.
