Hi, Ardith Hinton!
I read your message from 29.06.2019 16:24

 AK>> When a person is in a company of friends he never speaks formally.
 AK>> And he should not to. It is too loathsome, IMHO.

 AS>> Correction: "should not" or "ought not to"
(depending on what you
 AS>> mean).

 AK>> Is it true, Ardith? Can I replace "speak" for "to"?

 AH> I agree with Anton that "to" as you used it here doesn't work. IMHO
 AH> what he's suggesting is that if you don't want to overuse the
 AH> verb "speak" you could correctly say "he should not
(do so)" or "he
 AH> ought not to (do so)".

I meant something like this:
-----Beginning of the citation-----
"Instead of which," I said, "in a month's time I take the
most important examination of my career."

"I should advise you not to." (Ch. Snow)
----- The end of the citation -----

I.e. the main idea (I take the most important examination) was replaced by
"to", so that to be shorter.

Bye, Ardith!
