We're big on those Aaron/Erin vowel mergers over on Usenet. Even have sets of abbreviations to refer to them: CIC for cot is caught vs CINC for cot is not caught, PIP for pin is pen vs PINP for pin is not pen, and the biggie: MIMIM for Mary is marry is merry vs MINMINM for Mary is not marry is not merry vs MIMBMID for Mary is marry but merry is different. There's also horse is/is not hoarse but for some reason there are no abbreviations in common use for that one.
"Aaron" and "Erin" are related to that last one but not entirely synonymous with it. Also unrelated to CIC/CINC is that some people use different vowels in "Ronnie" (a form of my name that thankfully I seldom hear) and "Rani", which I noticed when a young woman from India with that name joined our office. As a native SoCalifornian, I'm theoretically not supposed to make any of these vowel distinctions, but it seems I've been influenced by all the radio announcers I grew up listening to and have an accent that doesn't actually indicate where I'm from.
On the subject of auto-correct, I was recently using the note pad function of my iPad to note an address in La Jolla. Living in San Diego, I am well aware that La Jolla is one of the most expensive real estate markets in the country, and it appears that the programmers at Apple Computers are also aware of this. My iPad auto-corrected "La Jolla" to "La Moola."
Re "boy's room". I would not use any apostrophe at all. For me, it's the "boys room", a room for boys. On Top Chef, they just added an apostrophe to "Judges Table", making it "Judges' Table". I'm sure people were complaining, but for me, there's nothing wrong with "Judges Table".
Am I wrong?
They seemed to be leading to it in the show, but Grant and Martha never really weighed in on whether BOYS with no apostrophe would be correct on its own, i.e., without ROOM following it. My feeling is that nobody would have a problem with it in that form.
Don't know if the signs are still there as the business has changed hands several times since I last visited, but one restaurant I used to go to had doors labeled GENTLEMEN and LADIE'S. I think that belongs under the heading of "worst of all possible worlds".
Re "rentals" for "parentals", I imagine it comes from "parental units". No?
