We underestimate the impact of passage of time on our lives. Over the years, while we live apart in our respective part of the world, a lot will change, either for better or worse. It is not as if the reunion failed, it just meant different things to different people. To some people, it was a reminder of things they couldn't achieve, people they couldn't become, a live they wished they were privilege to live. That reunion reminded them of some of this, and when these things comes to mind, the feeling is not always pleasant.
