Thanks LJ -- I had never heard of it before and I doubt if I could enter my pin number backwards in any case. Only my fingers know the code and when I had a machine with a different key pad I was really messed up.
Now I only have to struggle with Derly.
You're asking for trouble, Cardy. I'll bounce you around like a rubber ball. :)
Snopes. com is a love of mine. There's fascinating stuff in there if you give it a look. You'd be surprised what we thought was true isn't and vice versa.
