Important Apostrophe and a Tenant who is a Mysterious Lady

It should have said St John’s - with that apostrophe! So many omit the little mark. How could they, when its presence or absence gives us one meaning or the other? A tenant within these apartments who is a mysterious lady, placed the absent apostrophe on that poster, kept this nighttime act a secret, and crept away. St John was a saint we remember, on the twenty-fourth of June: it’s St John’s Day. And this little mark marks that. Without this modest mark, this little apostrophe, we have a plural, not a possessive. So how many Johns were there? Or are these apartments named after just the one John, as we’re told - the one that has that little apostrophe? Often do I wonder who the mysterious tenant is, the one who posts missing apostrophes.
