do NOT, I mean do NOT become friends with her first. the ladder theory is true whether you think it is or not. once she thinks you're a friend, you're fucked in the ass. you will not get what you want. this fucking sucks. learn from my mistakes please. this is very true if they're not mature, as the girl will want something that is out of reach for them. they want a challenge, they cannot realize something that is good for them if it's right in there face.
