There is a world of difference in explaining your work to someone you've never met before on a problem you've never seen in an environment you've never worked in. Versus explaining your code to your coworker whom you've worked with for the past X time who understands some of your eccentricities or idiosyncrasies and without a pass/fail judgment lingering over your head like a sword of Damocles.
