You're Only as Sick as Your Secrets

"The only people who can keep a secret are the ones who don't know it."
The Chemical Buddha found this out the hard way when he told some very personal information to a friend who said he wouldn't tell a single soul. And he didn't tell a single soul. He told several souls. Who then proceeded to tell two friends and that person told two friends and so on. The next thing The Chemical Buddha knew, everyone was talking about how he liked to shave his initials into his pubic hair. Not only did he learn that you lose control of a secret once you tell someone, but people won't pass on a secret that's not interesting. For instance, no one talked about how aerosol cheese was his favorite food.
Are you someone people trust with their secrets?
What do you know about yourself that's so secret even you won't acknowledge what it is?
