If your everyday life doesn’t provide you enough opportunities to experience passive-aggressive behaviour, covert aggression or emotional manipulation in general, consider getting married. Marriage seems to drive people to new heights in this area, both in dishing out and dealing with it. When you tire of the same-old, same-old manoeuvres, children can add some interesting new twists. And they don’t even need to be able to talk to play important roles.
I just can’t develop a taste for it. I can’t imagine anyone really likes those aspects of a formal relationship, but I suppose most people are able to end up labelling them a price worth paying.
