What would you do..?

If you found out something about someone close to you.. something I think that person would rather keep a secret.. what would you do?

Confront that person?
Just let it pass by?

If confront.. how would you do it?
A subtle hint?
An outright burst of anger?
Make up a story about yourself being in that person's shoes, pretending to ask that person for advise (and hope that.. well, that person can at least see the similarities and realise that you're actually referring to that person..)


Or should you tell someone else? Confide in another person?
And if yes.. who would you confide with?
A common friend?
Someone who doesn't know this person - at least their feelings won't be biased eh?
