Thanks, man. :) Good luck to you with regards to who you're pursuing, too!
I wasn't able to update sooner, but basically I sent the guy an email yesterday morning to casually ask if he was good for lunch. He replied within the hour that he was... and that he'd like to bring a mutual friend of ours (a guy).
Well, I wasn't about to say 'What? No, I just want to have lunch with YOU' but as that mutual friend works closeby and does happen to be good friends with each of us, I agreed (privately, grudgingly) and we met up together for lunch.
The conversation was mainly between our mutual friend and the guy, though I was prompted on occasion to join in. They were mainly talking about some wild party they had been in so it wasn't exactly the ideal conversation for me to try and interrupt. I let them talk and injected a joke every now and then for fun, and then it was time to get back to the office.
This wasn't exactly the kind of thing I'd been expecting, and I have to admit I was extremely discouraged by this. It's like he doesn't want to see me on a 1:1 basis at all anymore.
The only thing that was vaguely surprising on a more positive note was that when we parted ways, he touched my shoulder and patted me as he said goodbye, which is something he's never done before (i.e. touching me), and he did it in front of our mutual friend.
But still, like I said, discouraging. No contact has been made since the lunch. Any thoughts as to where this should go now?
