I hate this question. I generally say I work freelance in tech/marketing--which is true, as this is the bulk of my day.

For the most part I am out to my family and close friends. I used to be much more cavalier about just telling people what I do, but I kind of became a "Character" rather than a person. Now, I am much more private unless it is important for someone to know as this would not just affect me, but those close to me. Also everyone has kids and I don't want people to think that I would be a bad influence or something.

I am lucky as "What do you do for a living" is considered a pretty invasive question here, almost flat out rude.
