rancher, lots of people have a "sharp memory"; I have a "sharp memory", too. How about that?! Let's start a club! Really, it's somewhat condescending to suggest that your memory is so "sharp" as to be infallible. No person's memory is infallible. Scientists the world over will gladly fill you in (condescension intended).
Alas, you refuse to even admit the possibility that you could be mistaken ...
On the other hand, I surely hope that you are right in your recollections! We always gotta have stuff to search for ...
Cheers!
