Well, sorta overheard.
I have my students keep a log all semester of dialogue they overhear. They’re always wanting to copy it off TV shows, which semester after semester, I must inform them, doesn’t count. This wouldn’t count either, but it’s fascinating to listen to real people talking. Under stress.
The other fun thing is reading the comments. Some are to the effect of “how did they get that nice apartment…?”
If I were the teacher and you turned in this script… would I say, “Nobody says ‘dude’ that much in real life…” ???
