What To Do?

This is from an email I just got from a woman I don't know:

"Hey, there...how are you? I'd love to see you and catch up...any chance you'd be available to meet for dinner on Friday (5/30) around 7:00pm? Let me know...thanks!"

Her website is her email address, and she is a 40 something actress in New York City. I actually sent her a massively apologetic email explaining that it's been a crazy week, and I've just been so swamped, and if she wouldn't mind just... reminding me where we met. Ugh, I hope it's really not someone I know.
