Well Spidey... ya just gotta decide if your spidey sense is tingling
ok ok sorry i couldnt resist...
anyway... i would consider it quite flirtatioius... i would go with what harshaw says... i would say flirt back... and if she responds positively ask her if she wants to go see a movie and get some icecream or coffee or whatever afterwards... and see where that leads...
either that or start sneaking around the bushes in her yard staring in the windows watching her sleep...
