How do you get yourself to the head of the pack and stay there? What do you need to do in order to catch her attention and make sure she isn’t searching somewhere else for someone else? That is really the trick here isn’t it, you want her attention to be on you, while you ensure she won’t be looking anywhere else.
With this in mind you must understand it will be extremely important you give her a first impression she will remember, and one that makes her wanting more from you. Your goofy prop item is there to help you do some of that, although, this item should bring you some attention throughout the room and not just with her.
Remember, at this point you have planned your approach, you have your list of questions you might be able to go up to her and ask, and have it narrowed down to just a few rather than a list that would give the book War and Peace a run for its money. You have also worked the room and scouted out how she is mingling with other guests, so now a few more questions.
