There's is a scene in Broadcast News where Holly Hunter's character unplugs her phone and sits on her hotel bed and cries. I can't remember the exact details but I think she times herself and at the end of that several minutes she sucks it up, plugs in the phone and gets on with things. I was 17 or 18 when that movie came out and didn't quite grasp her sobs at the time.
Now? Oh, yeah sister, I sure as hell do. But silencing my cell phone lacks the flair of unplugging.
