Hi Maggie, I guess perhaps it wasn't clear to some of us (perhaps a lack of reading skills on our part) that you had acknolowged the mistake. I at least, had the impression that in the face of mounting evidence, you were still defending your original position.
One thing I will often do, is to pose questions, avoiding statements of fact unless I'm sure, as I did here:
I would have to admit, I know nothing.
So,I'm cool with respectful rebuke.
