I feel like these fun activities are created by extraverted managers who think that because they get energized by social interaction, everyone does. I always clearly explain to them that I'm an introvert, and I get exhausted by excessive social interaction and I need quiet recharge time. I tell them that I'll happily go to team activities if they are during work hours, but out of hours I'm in my own, re-charge time. No exceptions (and hold them to that) I have found most managers are understanding when it's explained like this.
