It depends.

Sometimes it doesn't really matter because people don't pay attention... and when they do, they talk shit behind your back... they might just act like you don't exist and copy, mimick, and/or mirror you... which gives you some control.

Good rulif thumb is to assume someone's always listening.

People are going to do what they're going to do at the end of the day, and trust isn't really something that is sustainable in the long term.

Eventually, there's always a backstabbing, misdirection or just out right lies.
