C.B.
I try not to discuss things I don't want the kids privvy to in front of them. If there is a lot of "cover noise" that's one thing, but when it's quiet, then myself and the other adult can either go to a different room or wait until later.
Kids don't need to be and shouldn't be privvy to everything. They don't have the life experience to put things into their proper context or to keep their mouth shut if the subject is confidential.
