You start zipping the bag, because you are just done with surprises that pop up from it every once in a while.
You start zipping, for you not to think about it.
Fast, faster, even faster.....
Until the rate of your zipping starts decreasing, one by one.
Until there is no more zipping to do.
But you are left with the bag.
The presence of the bag starts fading away into the place in your brain with all the distant memories.
Until the bag in itself seems like something from another lifetime that happened to someone else.
Things fade into the ordinary once they are reduced to that.
There has been no tested or proven methods to retrieve the bag again.
