Remember the Details of Their Life
Usually, people will understand if you forget their child’s name – but not a narcissist. They will never forgive you and will continue to hold it above your head. They can use it against you later if they want. Therefore, do what you need to do to write down any details about their life that you feel you need to remember.
You don’t need to memorize them, but you might want to keep the note handy, so you can quickly look at the information when it pops up. It might also be a good idea to review the information before you need to meet with your boss because you never know what they will say and when.
