Even if you've practiced a million times what you want to say when you're introduced to that drop-dead gorgeous department head in Accounting, it's easy to lose your way in the heat of the moment.  And it's often when you blurt out, "Oh my god, you are even better looking up close!" which you will regret until the day you die.  So keep practicing.  And write it down, if need be (anything to prevent a faux pas).  Just remember that the object of your affection may be mesmerized by you, too.  Especially if you happen to be wearing a rare piece like this one of French blue rounds and faceted carnelian.
