I agree 100% with Betelnut. I'm an introvert, but I certainly enjoy parties and socializing, and can easily hold my own. Plenty of people have expressed surprise when they find out I'm not classified as an extrovert on the MBTI.
At the same time, I really, really enjoy my alone time, never get bored when I'm by myself, and I do need time to recharge after a big party.
I think a lot of those thoughts, while funny to read, really miss the boat, and just feed into the misconceptions about introverts vs. extroverts.
