What do you think about people complaining to their partners about them having a private life?

I think they don't understand the value of time to give each other. They don't appreciate the life of the other. All they want is to have everything for themselves, for their expectations. If they truly love them, they will understand the importance of privacy that each of them needs even though they are together. They want the other to care about them but don't realize that they are the ones that should care about the other. Care about their need for privacy.

In a short way of saying: They are selfish.
