Haha, my sentence was a little ambiguous... I didn't mean that all my martial arts friends are women who like to dance with hot men. I meant that all my female martial arts friends are women who like to dance, and all my male martial arts friends have hot bodies, and those two things are what people notice when we go out as a group - that the women are all really into dancing, and that the men are all hot! Hahaha!
Oh, and as for my flatmate giving you the wrong number, sorry about that - she just didn't want her boyfriend to have to kick your ass.
