Sorry, you're right...I was knew that, and then typing out DOT's name, it just came out Treasury instead of Transportation for some reason. My bad.
You did the same thing I do a great deal, which is why I detest acronyms.
DOT = Department of the Treasury
DOT = Department of Transportation
I had a fifth-grade teacher who insisted only lazy, slovenly people used acronyms instead of taking the time and trouble to write out an entire term. And as so many acronyms have more than one meaning, sometimes while one really remembers the one he's referring to, a different meaning of the same acronym comes out.
I recall freaking out one time--I was pretty young--when I learned that in the military, sometimes it's
mandatory to use acronyms on official forms.
