tell them that you double penetrate thier daughter on a webcam for a living
actually I just tell them I do website design and if they push it I tell them I work for adult website companies building sites that use an age verification system to keep minors away from adult material on the internet. that way adults that want it can see it and it keeps kids out. It's a fancy way of saying AVS but most people I've found are pretty resonable and are okay with that. If they are offended by it then I just leave. Life is short and I'm not going to waste it on people who think I'm some kind of urchin.
