I was concieved in the USA, born in Salzburg, Austria, back in the USA before I was 3 months old. About 6.7 decades ago (I did not notice the change at the time, so I wasn't tricked). But I spent 2001-2018 on Islands in the Indian Ocean, the Western Pacific (close to the equator, from 7 degrees South to 15 degrees North and all around the "Sandbox Zone" & the "Ring of Fire Zone".Been in the USA for a bit over six decades now (my arrival coincided with my first breath). I knew IMHO; but never would have guessed what IMO and IME was supposed to mean either.
I, too, knew IMHO and guessed correctly at the other 2. But I could have just as easily been wrong.
