If you got a k-close, you must have done something right, or maybe you just looked right, or maybe she'd just been knockin back too many jd's and fancied a quick snog!!
Personally, I wouldn't use that line because I think it acknowledges her too highly, and gives her what she wants. On those types of girls, I believe Mystery loves to neg them all the more. Maybe if you did use your line, you could give her attention for like 3 seconds, until she starts speaking, and then do what he does and say "Oook, and back to me". Either way, keep making her beg for attention, and then perhaps play a few games with her to keep the interest.
Don't ask me about the next bit (Isolating and closing), cos I'm not the best at it, and besides, if you k-closed once, I'm sure you can do it again
