So as we know from previous sessions, people really do change. And as we grow and develop within a relationship, we have to find ways to transform that relationship in order to make sure that is mutually gratifying for both parties. So in this session, one of the things we're going be talking about are some of the strategies and methods that we can use in order to help transform relationships. But before we even get there, Dr. Tsang, maybe you can explain what kind of relationships would need to be transformed. >> That's a good question. I think the tempting answer would be every relationship, right? [LAUGH] But like we also talk about people who would prefer to keep a relationship for a long time without necessarily making any significant change to them. Those relationships do exist and they are valued by some people. So I guess there might be some relationships that do not necessarily need drastic transformation. But even with those I would add that like it might not be a bad idea to be checking in every now and then to make sure that the relationship is actually working. And this is why we always emphasize good communication between the partners in any relationship. But other than that I would say most relationships would go through some kind of transformation. If you think of a sort of like normal socially scripted relationship in the Western world, it would be like people who met and dated and you know, decided to be together. They might go through a phase of engagement. Some people would start living together for a while. And then maybe they get married or they don't but they stay together. Some people would like decide to have children and raise a family. Some people don't. And then the feeling, the mode of interaction, and the kind of things that they do together, I believe would change, right? So even if we're talking about like personal significant relationship that is supposed to last for a long time, there would be changes. And then of course there are relationships that are by nature time-limited, like the friends you have at kindergarten, [LAUGH] or elementary school or high school or college, your relationship with your teachers, your ballet instructor, or whoever. And people that you work with, like if you work in a company and your coworkers, your relationship with them would last for so long, right. And then your relationship with your teachers, and you know, maybe even other family members. And then the current state of family life, and you know that there are people that you're connected with through marriage. And then all of a sudden your cousin, or your brother, or your sister gets divorced and then you're no longer related to these people in the same way. So, those relationships would change, right? So, there are all sorts of transformations that we can imagine.
