My family doesn't even know I do IT work...
I've led them to believe that I am doing pharmaceutical research (My degree is in Organic Chem). I've seen too many of my friends end up losing sleep to help a family member fix something stupid, so I decided to hide my IT prowess.
I've been referring them to a friend of mine that still live in our old neighborhood and runs his own shop. I do work for him periodically to make up for the costs of supporting my parents. He is excellent at the most common 95% of problems, so I'll help him out with that last 5% or on jobs that require stuff that is out of his depth.
