Don’t expect accountability. This point has been touched on earlier, but understanding that they won’t take onus for their behavior saves a lot of time and energy. If you want to verbalize their responsibility for their actions for ease of mind, that’s certainly appropriate. But don’t expect them to take what you say to them to heart.
It’s incredibly challenging to never get an actual apology- an “I’m sorry” followed with a “but” is an excuse, & contradicts said apology.
