complex or simple ephemeral or permanent

Human beings, such a complex creature, sometimes can just think things in its most simple way. However in other time, they may twist themselves up.

Just at the beginning of this week, I felt so happy, not for myself, because obviously I am in such confusion about my future or my life, but for SSL, who just got the offer from the company he is always dreaming of. Along with such ephemeral happiness, suddenly, another fact jumped into my life. In less than a month, he will go to Shanghai for his internship at that company, together with another team member of the lab. Maybe such feeling of leaving is so familiar or maybe I am such a kind of people who will not be used to leaving people who has been part of my normal life, this is the season of beginning of school, but at this moment, just as the leaves following from trees, all the feelings and thoughts still remain in the last season - the graduate time. Why I am feeling so sad?

From the perspective of life, in a way, there will be three kinds of people who will be appear in our life. The first are the ones who will be thought of when in  sad, helpless and suffering. The second are the ones who deceive you or make use of you. The last are the ones of strangers. However in my point of view, I really think that there will another kind of people between the strangers and the ones who will be in great position in your heart - the one who just has walked into your life and accompanied for a time, but finally they will walk out and leave away, only leaving you some special memory or nothing. In such kind of person, there are your mates of kindergarten, junior school, high school, former co-worker, teacher or the travelling companies and so on. It might be possible that you can't even remember their name. I believe, in most people's life, the number of the first and second kinds person would be much smaller than that of the two latter ones, just as the brain to choose tiny part of everyday happening to turn into memory. That 's also the reason why those two kinds of people will be special in our life.

Maybe it is time to move on, just as the end of the travelling. However I still believe if some one already as one of the fist categories people in my life, the relationship will definitely not be degraded. But others might not think so. Then such uncertainty or the feeling of losing some precious things or feelings make us so anxiety then it will become sad. In another word, the fear of changing is the main reason.

Nonetheless, just as the old saying - if moving tree, it will die; only if human changing, he will be survive, people need to change themselves or the environment for the better improvement. So maybe the best way to let some one still be in the most important person in your life, is to hope him to change into the way he wishes to be and be there if he is in need even he doesn't know that there will be some one.
