>Lol well teaching this professionally surely makes me some form of authority (albeit of course not the authority!) on this subject.

no, it doesn't, because even if you could *prove* that to us (which i'm sure you won't), your authority doesn't trump evidence and facts.

>This incorrect distinction is what I was objecting to, because of course we can use both the indefinite and definite articles to refer to either real or imaginary mirrors.

and, as i said previously, it's not technically grammatically incorrect, it's just bad style/form. and i reject your argument that bad form is "acceptable" just because its common.

your inability to parse what i've said here and your insistence on pursuing a needless argument really doesn't add credibility to your position that you should be considered an authority-- or your  claim that you're an english teacher.
