How can I do this
Answer on How to strike up conversation with girl you've been stalking on facebook?
You should know enough about her life to write a book. Use the information you've accumulated through months of careful observation and implement it in an icebreaker. You know all of her interests and best friends by name, as well as her favorite quotes and TV shows, you know where she likes to go and what she likes to do when she gets there.
Go get her, tiger.
