And, more often than not, we seem to remember the nearly empty bottle more than the nearly full.
I did not intend for this to have any symbolism with our own lives, but it can't help but rear its ugly head that we seem to remember that bad points in our lives better than we can the good.
There are occasions, however, when we seem to remember the mid-points, especially when things are going from the bad to the good. These are usually after we have decided to gain control over ourselves again to make the better things happen.
It's funny what you think about while looking at an almost empty bottle of ketchup.
