Thanks for your interest. I think we have a lot to offer each other.
Of course you have questions, let's chat and get to know each other. Here's a list of references.
You'd like to do a background check? Sure, I understand. No, that's cool, I'm not offended -- due diligence and all that.
Facebook account login? You want me to give you my username and password to Facebook?
Well, thanks for your time but I really must be going. No, there's nothing to hide but this crosses a line.
No hard feelings, I'm sure you understand.
