Yea I was kicking myself after, because it was a one-off: her flatmate had left and she was alone that evening and wanted company. After that night she didn't want to know, asked her out for a drink 2 times to no avail.
But like i said, she seemed a bit of an oddball anyway. I think she is a plastic surgery addict with body dysmorphia. Just kept asking how her new nose and chin looked, showing me old pictures that looked EXACTLY the same, and asking if she now looks a lot better. And big framed pictures of herself scattered around the flat. Weirdo.
