Have you ever stayed away from an event, because you did not have anyone to go with you? There is nothing worse than standing around a room where nobody will talk to you. (And thinking that everyone is talking about you.)
When planning any event, think of those people. Always have one or more people in charge of seeking out people standing by themselves, who can introduce them to others. Make sure no one at your event is left standing alone. Or else, next time they won’t be there at all.
