My wise mother told me that you don't really know a girl until you've spent at least 500 quality hours with her. That's 500 wakeful, interactive hours. It's usually enough to become acquainted with her mood swings, her friends and family, and her true nature once she's off her best behavior. It's excellent advice, and I wouldn't allow a relationship to progress until after reaching that 500 hour mark.
