I think a lot of things that are being classified as mind games are not truly mind games with a negative effect or negative intention. For instance, when parents do 'rona dhona' over a certain issue, it is not necessarily blackmail or manipulation all the times. Sometimes, they are TRULY disappointed and sad over a certain issue and not intending to manipulate at all. So, if a parent is sad over something and it is being perceived as a 'mind game', then there is definitely something wrong w/ the perception.
When a girl or a guy plays 'hard to get', it may not necessarily have a negative outcome or done with a negative intention. Both parties involved may even be liking the whole thing and find it challenging.
I think if we are going to perceive each and every human emotion as manipulation or mind games, then it would become difficult to trust anyone really.
