So, I'm not asking for advice. I'm not asking what I should do. I'll figure that out later. No, I want to know what you would do in an analogous situation. Leave a comment, eh?
Suppose a cute girl (or boy, or spivak, or robot, whatever you prefer) contacts you thru an online site. Just a basic one-click 'hi', without actually saying anything. You, on your way out the door when you get it, reply in kind with the intention of following up later. Then you forget to do so. When you finally do, you find they already have, asking "And then?". You reply, explain why you hadn't replied yet, and say a few other things, like "like the hair", and "Do you work at , I think I recognize you.". You also give your real email, 'cause hey, you'll reply a lot faster that way. She (he/it/they) reply to this message, by email. You reply to that. Then, nothing.
