Closure is important.
I think that I am a person that needs closure in pretty much everything.
Whether it be a friendship, a graduation, or a show there is always one very specific point where accept that something is ending and then from that moment on I'm fine. I can forget about it; move on.
Without that moment, everything in life just ends up hanging around in mid air. Nothing is finished, nothing is put away. It's chaos.
Change is only good if you have closure to what is ending. It's the old idea that you have to throw out a pair of old shoes every time you get a new pair. (I never end up doing that, but you get the idea) In order for something new to come, the old must go.
That's what I think.
