Personally I'd consider a deeper reflection and ask yourself whether she was truly attracted.
It is easy, and as I've found, almost common, for women to fain interest in a social situation... rather than creating what she'd determine to be an awkward situation.
For you to have a 10 minute conversation where most of the talk comes from you (strike 1, you'e already doing the majority of the investment), I would question just how much she actually contributed.
She could just have easily been sitting there with a silly smile on her face, thinking "What the hell does this guy want? He's just told me his grandmother can drink faster than a boat, and now he's telling me random dribble".
I'm not saying this is the case, but rather offering an alternative view to dissect unsuccessful approaches.
Believe me, I've had my fair share. In fact, to a stage where I purchased an audio recorded and listened back on my sets in order to properly review and highlight areas to improve on.
If you have any incling, I would suggest checking out this Infield Daygame Pick-Up.
It was of a total 'yes' girl who was devilishly attracted to me from the start of the approach. I supply an analysis throughout the approach, and it quickly becomes quite clear as to what lengths a chick who is TRULY attracted to you will go to in order to generate conversation and KEEP YOU engaged.
