Everyone knows what it’s like to be sad. Your eyes can always tell, even if your lips are projecting a smile. But sad can be anywhere from a temporary disappointment to a long-term depression.
I would not be surprised if someone told me that a lot of people in London are sad. I mean look at the weather. In my 6 years here, I am still to experience 7 days of uninterrupted sun. It’s preposterous how much the weather can affect our mood.
Just like happy, sad is a state of mind. It is in our power to change that state of mind. Or to keep it. Very often, admiring a work of art can be associated with sad personal memories or mementos from the author’s life. And you can definitely tell if the painter or sculptor was deeply affected by their own environment, to the point that their sadness is looking at you from below the surface.
