Here's an example of how one measely little word can change everything.
Tears For Fears has a song, "Mad World" which has been covered by more than one person. There is a line,
"Hide my head I want to drown my sorrow."
All right. Now check out what it says on one of the covers. [I won't say who it is by so as not to shame them. :) ]
"Hide my head I want to drown in my sorrow."
!!! in? It's a tiny little word, doesn't do much. Oh wait. Yes, it does. That makes a huge change in the meaning of the whole concept! Be careful, people. One word makes all the difference in what you are saying. ;)
By the way, a fun tidbit: The original song by Tears For Fears is quite speedy and catchy. For the movie Donnie Darko Michael Andrews and Gary Jules covered it. [They are not the ones who added "in."] Their version is very slow and melancholy. It's an entirely different kind of change. I have to tell you, if I had heard the Tears For Fears original I had forgotten it. After hearing Andrews/Jules' I found the original no good at all at first. Quite jarring. I've since come to appreciate both equally. But here's the corker. Roland Orzabal and Curt Smith of Tears For Fears prefer the Donnie Darko version as well! They said the song had been improved. How about that?
