Try this
- Use a short phrase that signals the subject should move out of the group setting.
- Choose whether to schedule a private conversation later. Avoid adding arguments while supposedly deferring the discussion.
A worked example
“I want to discuss that, but not in front of everyone.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Do not use privacy as a reason to prevent the subject ever being discussed.
