Do you have trouble explaining your job to people?

Explaining my job is trivial compared to the insanity I cook up in my spare time.

Oh, so you like gaming? No, I'm actually not playing the game. I'm building a mod for it. Erm, okay, so this is for other players then? No, I'm mostly building it for myself. Ah, so you haven't put a lot of time into it yet? Roughly 12 years. What? So what does the mod do then? It plays the game for me, and publishes in-game metrics to a monitoring application, so that I can see the progress of the game in an abstract form while I'm on the couch, thinking about how to optimize the automation further.

Regular fun stuff.
