Do you mean sexually attractive? Or just interesting looking? I'll initiate conversation with interesting looking people (that may or may not be sexually attractive).

By dancer I just meant someone who does modern dance, she was a friend of a friend (I have some odd friends by this websites standard I think).

Oh I know I should develop more marginal connections. It simply feels false to do so though, that I am doing so in the hopes of exploiting them, rather than finding them particularly interesting in their own right. I would rather not be cultivated in that fashion.
