Replaying
After a tense interaction, do you replay it in your mind? Do you “re-live” it, in a sense that your emotions return to the state that they were during the unpleasant experience?
Have the presence to stop yourself. Take a few deep breaths. Consider why the interaction troubled you so much. More importantly, consider this: does it help to obsess over the interaction? Does continuing to recall the details make things better?
Probably not. So if replaying it doesn’t help, what will?
