I politely knocked, and was met with anger.
I didn’t even know you were in there. But, there’s a door right? Closed, yes, but why I knocked. And, the space you occupied is not your own, right, which is why I was knocking right?… because I had an interest in occupying the space.
People are more or less aware and considerate. Many are so utterly consumed with themselves… to the point they can’t see others as they (others) are and as they (others) are doing.
