I just leave this here:
Found in [REDACTED] in Munch.

In fact, all language is made up from individual metaphors. That's all we have.
In art, the picture does not have to be a metaphor, of course. It can simply be a record of what someone might observe. Still, your picture is interesting enough to be amusing. More than that it has a message within it by the person who tied the string: "Please do not open this door, I wish to keep you out, even though you could easilly get rid of the string. I hope you will respect my inherently obvious wishes!"
At this point, your photograph has already worked its way beyond being merely a simple record of what one might see.
I merely wonder what else this might represent, such as the difference between what one can do and what one shouldn't do. After all you have shown a point of vulnerability in someone's attempt at some "defense" of privacy.
I would argue, that when one revisits this unusual photograph, it works to be more than humorous and can lead us to explore ideas of vulnerability of others.
So that is why I posed the question.
