Having dealt with narcissistic people, that is still pretty ok. I can live with listening to a person talk about themselves.
It is the person that has to change all the topics to be why the listeners need to do something for them that drives me mad.
Had a bite? They skipped that meal so need a bite from your snack drawer or whatever you purchased.
Did you have a good night sleep? You did? Better be ready to listen to their insomnia story. You could not sleep? Better be ready to listen to how their sleepless night was worse.
I do not care if you think you are the most beautiful person in the world but I hate it if you think that I need to donate my resources to your campaign. Or how I am a bad person for not offering condolences or encouragement.
