Introvert/extrovert isn't a personality type, it's a way of gaining or expending social energy.
If being around people wears you out, causing you to need time alone to recharge, you're an introvert.
If being around people gives you energy, you're an extrovert.
Introverts can be sociable and extroverts can be shy. I'm an introvert, but I can be plenty sociable. However after the party/event/gathering/whatever, I need time by myself or with just my wife to recharge my batteries. And sometimes I just don't have the energy to be around people.
