upon further review, I'm going to take GManiac's advise and leave out the "disappointment" remark. Since there isn't an easy way to address the issue of neither of us having contacted each other, it's best left without saying anything.
So I can tell them I'm "currently available", and look forward to hearing from them if they are still interested. Of course if they aren't interested it really doesn't matter what I say. :)
Dammit, that's why I said!!! (but I completely agree.) good luck Don.
