obvious secrets

If someone tells you something personal, do you go tell someone else?  even if the first person didn't say, "please don't tell anyone", isn't obvious, isn't it? that if it's personal it should remain personal.
I just found out that someone told other people something I said.  No, I didn't specify that it was a secret and it's not something that other people shouldn't know.  It's just something that was personal and unique between that person and I.  One of the two other people that heard it is not a close friend of either one of us... and that person told someone else.

Anyway, let's remember that if what we are told sounds personal, we shouldn't go tell other people, let's keep it personal.
