I can't remember ever seeing that, another screwup correcting someone else's - damn I'll leave it but now have a bad habit of what was given as an earlier example!!!) - but thanks. It's endemic, even reporters in web editions (and perhaps in hard copy) do it way too often. But I almost did it myself upstream ;-).

I developed a couple annoyances of my own. The first seems to have trailed off and it could be my poor vision or even keyboard (watch, I'll start doing it again), but if I read something I'd written after it's too late to change, I'd terminate with two periods as if one wouldn't suffice.

And the other annoys me at myself no end, but I seem to have the inability to close many uses of parentheses and only catch it if I take enough care to edit which, in haste, often I don't bother. Idiosyncrasy or idiocy? Probably both and more.

I did that once. Luckily everyone else thought it was intentional :D

I also do the same thing, especially when I have parentheses within parentheses :~p
And, too many dots (periods); it has been a bad habit for a couple of decades.
