Hmmm, i may have a one track mind but i would have translated a comment like that as her fancying you. Rather than getting pissed off you should have got in there. Or, at the very least, taken it as a compliment. It"s similar to when you meet someone and they ask what star sign you are. They are weighing up the possibilities of compatability (allbeit in a very airy fairy nonsensical way). They like it even more if you enter into a good natured argument telling them that all that star sign stuff is rubbish.
