Life is just like a river. When we are in adolescence, we are flowing down the same stream with our friends, sharing the same environment. But when we are growing up, the river branches off. We have different careers, different values and different life priorities. With the common context disappearing, the state where we could talk about endless topics has also vanished. I used to feel really guilty for growing apart from my old friends, But it just happens all the time, I gradually lose connections with my childhood playmates, my high school classmates, my roommates in university. I can't change it. As time goes by, I gradually accept the fact. The connection between us is no longer about what we are doing now but who we were together. We were the keepers of each other's histories. We remind the other of our own roots and the person we once were. It's already an incredibly valuable and unique bond. I just feel thankful for that they provide support, laughter and companionships in one period of my life. Despite the distance and differences, they are alway a cherished landmark on the map of my life journey.
