Why do we have art? I think one reason is because it provides a connection. When someone expresses themselves through art, another person might find something in it that resonates with them.
I think we feel less lonely when our feelings are reflected back to us through art.
Maybe we feel something deep within us that we can't articulate, until we stumble upon a form of art that makes it clear.
And then we can share that art and experience it with others, giving us a way to build connections with each other.
So maybe that's the role of art, to create a shared experience that can bring people together and help us all feel a little less lonely.
