That's really weird. Until now, I finally realised that even friends have a certain kind of expiration date. There is always a period of time, you feel so enjoyable being with some people. You do all the things together, sharing stuff happened in each other's life. You go shopping, playing sports, texting frequently, and know all the news about that person. The mysterious complexity hidden inside human's mind, however, sometimes twists facts to something far beyond our imagination. Once after a while, people get alienated by the thoughts they created on their own. And for the most of the time, those things don't even exist. And that's what makes a friend expired. They just don't taste as good as they used to be. Like what we did to those rotten food in the fridge, we throw those friends into the dumpster.
Sounds sad isn't it? Plese don't be, because this happened to everybody. You dump people, and one day you'll get dumped by others. The feeling is mutual. So don't let these things upset you or affect your normal life. Maybe one day you'll find something precious again in the recycle bin.
