Secrets

Three friends were at the bar talking, and after many rounds of beer, one of them suggests that everyone admits something they have never admitted to anyone.
- Okay, says the first, I've never told anybody I'm a gay !
The second confesses :
- I'm having an affair with my boss's wife.
The third, John, begins :
- I don't know how to tell you...
- Don't be shy, the two friends said.
- Well, says John, I can't keep secrets.
