Will you give anything in order to interferce your past?

I realize once again, one thing that really important is time. The regret feeling after passing by a moment, is the worst feeling ever. When you are not powerful enough ti make up and rebuilt or undo a moment. For real, its time's fault. If there is no time, there wont be any kind of regret. But i was wrong, with time we shall move and act carefully. Yea, if you are a fool you'll think that there is still tomorrow ahead and probably do the thing later. If you are smart enough you wont ever think once there is later or tomorrow. If you had something to tell to a person you shold do it this second; else you will regret. I was moved for second with a drama titled operation proposal, which moves my heart to realize regret is existed in this world. I may had done something that cant be made up whatever i do. That sucks, if only i had a conductor time ir a fairy that can turn me back into past, i maybe would really happy; but that's not the fact. Yea, this is regret.
