That WOULD have been really funny! Unfortunately, . . .
As for me, I didn't respond, because I absolutely agree with you. However, I also am driven insane by buyers leaving you hanging! "Don't sell it to anyone else! I'm PayPal-ing you tomorrow afternoon" have been the last words I've ever heard from far to many for my taste (believe me, it only took one)!
So, I wasn't responding out of courtesy. I didn't want to steal the thunder of what you were saying!
But the other notion would have been hilarious!!! I wish I had thought of it!
