My apologies. I should have remembered that you do have a good grasp of the English language.
OTOH, I see that error of making a noun plural by adding the unneeded apostrophe and then the “s” so, so many times that I thought it a good opening to reinforce what Meade wrote.
Again, I’m sorry.
As I replied to her: “I know the difference between possessive and plural .... it was 3am here in Australia and tired, okay?”
That would be Mears.
