Own it. Always.
I like taking the time to remember and evangelize that wrangling 1's and 0's isn't always the simplest of tasks and all it takes is one of those digits getting out of line to cause a host of mishaps.
Finding that balance between stepping outside the problem and owning the problem can be tough during a demo presentation. I try to gain some perspective on it by thinking of mistakes in other professions and the repercussions of, say, administering the wrong medication to a sick patient in the hospital. "Did you code kill anyone today?" (I have a morbid side).
