What is your sims deepest or darkest secret?

Being in the criminal career, my Sim has many deep, dark secrets. He's great at hosting parties with his wife and guests that include his mistress and casual girlfriends without anyone figuring it out. He has a vault filled with stolen goods. And people dont realize his karaoke bar is really a front. But only Grim and he know the reason he keeps offing vampires. I think Vlad suspects, though. Watch your back, Vlad, Jack's revenge is close at hand. His true love's death will be avenged.
