What do you tell people when they ask what you do? I've most recently answered that I am a Web Developer. For some strange reason this leads them to ask: "Hey, can you fix my email?" I usually just answer with "um, no." and change the subject.
I've got a couple of easier answers these days. I'll occasionally tell them I'm a blogger, but that gets strange looks, and or the above mentioned email question. The most recent and certainly my favorite answer now is that I build robots. While that isn't really my job, I do get to build robots, and I have access to our lab after work and on weekends so it isn't a lie. So far only one person has asked me to fix their robot.
