This Thursday, you'll be getting together with a group of people you willingly have not seen for about a year. They're your family, but the truth is, most of them you don't know even as well as the mouth-breathers you work with. And they don't know you as well as they know George and Jerry and Kramer and Elaine. Therefore, probability of social faux pax is almost 90%, while chances of nervous tension are nearly 100%. How do you avoid being the bonehead who embarasses the entire family?
