I think introverts both gain energy from interactions with loved ones, and gain energy from being alone, and I think that's the same for extroverts. It's different types of "energy." I just don't buy that the simplified dichotomy is a good way of categorising, even if it's in some sense a spectrum. It misrepresents how human psychology works.
