I was thinking about chiming in on the original thread, and didn't - so here goes my 2 cents. . .
I also feel almost exactly the same way about my SM number. After using my WP # for YEARS and YEARS, I thought I'd have trouble memorizing my SM number as it just seemed like a huge endless number that doesn't have a seemingly "catchy rhyme" to it, but I "DID IT", too!! I finally memorized mine!!
As to the "M" word - - It also has always seems like a silly word. To me, Medallion is a NYC taxi cab. "Elite" always seemed a tad hoidy toidy to me. It felt a little strange doing Elite early boarding wondering what all of the infrequent non-elite travelers were thinking about us Elites, as they STARED at us - like the Chosen People - who get to board first - what did THEY do to be so ELITE!! Do I have a better suggestion? I'll hafto think about it! That should be a whole new thread, but would probably be closed, too!
