When you approach a girl, no matter how you might try to conceive your "intentions", she knows it. There is nothing you are doing that another thousands of guys didn't do. Girls know what a "pick up" scenery looks like and are very experienced in the field.It might be the way you look at her, asking her number, approach her specifically, etc If it smells like a duck, walks like a duck, quacks like a duck then it must be a duck.
