N closed a cute girl at my uni today (I'm a postgrad). We had a lot in common, she was pleased to talk to me.. only when I said my name I realised she knew who I was. I'd been on a couple of dates with a friend from her class - not that it lead to anything. She seemed glad to stay in touch and sent a pretty long text when I did, although she offered me her email, suggesting I should stay in touch that way. She clearly had some picture of me in her head because she said 'nice to meet you properly'.. as if we'd somehow met before.

Any way to make this work, or should I drop it? I don't know if she and this other girl are great friends or anything, but if she's going to be funny, I'd sooner not waste my time..
