Some people might have a lot of requests, they could insist, they could be complaining, and talk a lot.
Yet, I don’t consider that „energy vampires” actually exist.
I think that each of us has some weak points in our communication styles.
I also think that we should try to be receptive to constructive feedback.
Yet, at the end of the day, an annoying person could have good results, while a people-pleaser might not be a productive person.
