Sip a summer party beer admiring your assembly of all of your acquaintances in one location. Friends, neighbors, family, and work colleagues mingle and share stories while enjoying great food and drinks. Wait … maybe we don’t want all of those groups converging at the same time. In fact, it is usually best to invite guests who know several others who share similar interests. Drawing from multiple segments creates a party that is fragmented and guest who are reluctant to mingle. Certainly invite some people who don’t know others, but be prepared to help them integrate when they arrive.
