Dear Ms. Advice,
I have a little bit of a problem. There's this girl I really like, but I don't think she likes me back. I mean, I really like her, maybe even to the point of obsession. What can I do to get her to like me?
Frankly, if someone doesn't like you, there's not always a lot you can do to -make- them like you...without using underhanded tactics which will generally come back to bite you in the ass.
But, if you are interested in underhanded tactics that might come back to bite you in the ass, read the following two books:
1) Mind Manipulation: Ancient and Modern Ninja Techniques
2) The Art of Seduction
After that, check your hygene, your breath...and get a new set of clothes...
Then forget the girl, and find someone who likes you for you.
