Vancouver: With another weekend of pre-Christmas parties fast approaching, there are some do's and don't's to playing a good host. According to the BC Safety Council's Brian Lowes, ensuring your guests arrive home safely is key, even if it means not drinking at your own party, "You have to limit your own consumption of alcohol so that you retain your own judgement and ability to continue managing your party." One idea is to play tag team with your partner, "Couples often have, which one is going to be the designated driver, well, who's going to be the designated host." Lowes says having a plan for your Christmas party helps prevent any problems. If a guest is drunk, take away their keys and call them a cab.
