If you come, you will go. If you come you might stay but maybe you will just go. If you go, you could come back but it is possible you will not. Those that stay may leave in a day or two but at some point all will leave. Those that leave did not stay. Coming and going is a natural thing so do not expect anything to be certain. Being certain is for sure but if things are uncertain, you will not be sure. In that case there is no telling what will happen next. If you do not know what happens next, make the best of it and have a good time.
