It's always exhilarating to find out a secret about someone else. But after the buzz wears off, you're saddled with the responsibility of protecting someone else's secret. And most of the time, secrets are kept secret for a reason. Some are so salacious or illicit that if you accidentally let the truth slip out, it could literally ruin someone's life. Luckily, if you feel compelled to spill the dirt, anonymous internet forums exist for exactly this reason.
1.) From haelesor:
A coworker bragged (at work) about losing his virginity the night of his bachelor party but his wife still doesn't know and thinks they lost their virginity to each other on their wedding night. It's a VERY big deal to her and would most likely end in their divorce if she ever found out.
