A wanted something. A wanted B to want it too. A tried convincing B that she could do it if only she tried. B was scared. A sat for hours and convinced B that she had nothing to lose, that she could do it if she believed in herself, that if they happened to succeed, they would have a gala time and if not, there would have been the attempt itself, that losing did not matter, that making a fool of yourself did not matter, that B was more than she thought she was. A put in a lot of time, a lot of effort; just for B..
B got through. A did not.
