When I used to write freelance articles sometimes I would string for the local daily and weekly newspapers. As such, they would assign me local crime stories -- usually something that sounded interesting. "Naked man in rowboat with .22 rifle floating around shooting at birds" or some such.

I used to have one source inside the police department that could make anything at all sound boring. He would start each interview off with "Well, it really isn't that interesting, but I'm happy to tell you a little about it."

After 20 or 30 minutes of taped interview, eventually I would agree that yes, it really isn't that interesting.

Since then I've made it a point never to say something bad about your presentation or story. If it's rotten they're going to figure it out anyhow, and no point in spoiling the suspense for them.
