I sent the invitation and it didn't turn out the way you thought it would. It wouldn't have anyways, even if the stamp was used. Call backs are irrelevant, this opportunity has expired. Maybe. Probably not.
We've only got so much time on the books, and sometimes we have to destroy something old to start something new. The thing I'm destroying is not quite the one I want, but the choice was not mine this time. I guess its time for a new #2.
