I've learned some important interviewing dos and don'ts in just three years. Don't drink water if you're within earshot of the waterfall and not within walking distance of a bathroom. Don't walk and take pictures of someone walking a tightrope over your head at the same time. Don't pet rats before lunch. Don't walk behind cows after lunch. Don't watch a nose piercing on an empty stomach. Don't ask couples what they argue about most while they're in the same room. Do have batteries in the camera, tape in the recorder, ink in the pen, and gas in the tank.
