Even if you don't play any participant observation games, it's crucial to follow up on family events by debriefing with someone you love. If your brother really "gets" you, call him after a family dinner you've both survived. If you don't trust anyone who shares a shred of your DNA, report to a friend or therapist. Generally speaking, you can schedule a debriefing session for a few weeks after the holidays, when everybody's schedule is back to normal. However, you should exchange phone calls with your debriefing partners within a day or so of the family encounter, just to reconnect with the outside world and head off any annoying little problems, such as ill-considered suicide.
