Do you usually experience a let-down after the holidays or a wave of relief that the social obligations are over?
Option number C: A sense of satisfaction that I had a good time, and contributed to the enjoyment of others as well.
Well, no, not usually - but this time. Usually it's a small relief that it's over. Since I'm an introvert and have a limited capacity for socializing, it always feels good to finally be alone again, even when I've genuinely enjoyed the company of the people I've celebrated with.
