I have a friend who routinely give people what they want. If a person likes to be encouraged, she encourages them. If you want to be alone, she’ll leave you alone. If you want to talk, she’ll talk.
Further, if she knows you don’t want to do or talk about X , she will not bother you about X.
So what about the opposite? People who withhold. They know you want or you like X and because of it, you will never, ever get it X from them. It doesn’t matter if they are up to their eyeballs in X, they will keep this from you and observe your suffering.
Further, they will give you exactly what you don’t want and lots of it!
What signs or aspects would you associate with these behaviors?
