a big "thank-you" for not only teaching us semi-literates and/or fastidious grammarians

I questioned the usage, dear ASp, not the author of the usage ... unless someone takes umbrage with the description "fastidious grammarian".

Personally, I think all grammarians should be "fastidious", or what's the point of being a grammarian?

I would certainly not describe you as "semi-literate", ASp, nor Faldage as "semi-grammatical".
