As a relatively new programmer (1 year professionally, many years as an amateur) I've run into many situations that sent me running to Stack Overflow for answers that failed my meagre experiences.

Tonight I received the hardest question ever.

My wife asked me:

What are you working on?

The questions is deceptive in it's simplicity. A straight forward and truthful answer of "I'm working on a c# class module for monitoring database delivery times" is sure incite suggestion of attempts to confuse.

My second instinct was to suggest that it couldn't really be explained to a layperson, after very brief consideration I came to the conclusion that this would likely result in a long and sleepless night on the sofa.

The end result was a muddled answer along the lines of "something to monitor automatic things to make sure they're delivered on time". The reception was fairly chilly, I had to make many assurances that I was not insulting her ample intelligence.

My question is thus, what is the best way to discuss your work as a programmer with your significant other who is not.
