Maybe you're a Thanksgiving host who loves to welcome family and friends into your home for the feast but hopes to watch the last football game of the day without company, feet up, polishing off the dregs of a half-dozen wine bottles, eating a sandwich made from the tiny bit of turkey you managed to hide from those hyenas and making a list of relatives you need to apologize to tomorrow for some dumb thing you said and another list of those who'd better, by God, apologize to you. Presumably, you've taken the precaution of installing the locked security gate on your kitchen that you'll slam shut at 6:45, signaling that snacking time is over. Next, fire up the continuous loop of "Grandma Got Run Over By a Reindeer." When all else fails, etiquette experts agree, pepper spray is permissible for clearing the premises, but for that festive feel, be sure to use the Martha Stewart holiday line of spray, which comes in lovely seasonal colors and adds just a smidgeon of peppermint or nutmeg to that burning sensation in their eyes.
