That's what a lot of people don't get about introverts. Yes, I interact with people, and yes, I leave the house. I just interact with certain smaller set of people which I am not eager to extend on each opportunity (it may happen, but slower), and I leave the house when I feel like it - which may happen less frequently than some other people, so what.
I've always looked at introvert vs extrovert as how someone recharges their mental battery. I think of myself as a Social Introvert. I like socializing with other people when I'm recharged, but I need alone time to recover. When I'm done being social, I'm 100% done and can't be bothered to continue interacting.
