My Parents Still Don't Know...

[ILikeApples]

It's been almost 2 years since I have gone "pro" and my parents still don't know. All my friends and siblings know and I trust them to not spill the beans until I give the sign. The problem is, my parents (like most parents) are old-fashioned. They think that the only way to make a living is to get a job. I am afraid that if I tell them, they will both simultaneously have a heart attack. Any tips on how to deal with this dilemma?
