Just think of those 7 open questions
WHO will be going? Who should go with me? Who will the hosts be?
WHAT is the event all about? What will the format be?
WHEN is the event? Can I go, what are the timings?
WHERE is it? Do I have directions, any parking problems?
WHY is this event being held? DO I need to know some history behind it?
WHICH dress or suit am I going to wear?
HOW will I get home if I have too much to drink?! How am I going to be perceived if I get in that state?
