“If you are not excited about the event you are planning then how can your attendees be?”
Well, let’s see. “Attendees” (what happened to “guests?”) will be there to eat, drink and socialize and do other fun stuff while the worker bees/planners will be doing things like running around trying to find pitchers of water, having name tags thrown back at them, dealing with a toilet paper shortage, missing out on all the appetizers and cursing the fact that the event is the same night as a party/concert/play/TV show airing that they were really, really looking forward to.
So there.
