My colleague, Tabitha, covered some of your worst holiday disasters here. But there was one potential fiasco that didn't make the list: being responsible for a drunk friend's actions after they leave your house party. See, in many states, the so-called "dram shop liability laws" that were originally intended for pubs, clubs and other alcohol-serving establishments are not extended to homeowners hosting a holiday party, according to the Insurance Information Institute (III). Now that doesn't mean you should hit the cancel button on your Christmas Party e-vite. Just see after the jump for a few tips, from the III, about what you can do to make sure it's a safe and happy holiday for all.
