body: <p>How do I call the overrided method in the superclass from the subclass in Love2D?</p>
  
  <pre><code>Sprite = {}
  function Sprite:new(x, y, image)
      local self = {}
      self.x = x
      self.y = y
      self.image = image
  
      function self:draw()
          love.graphics.draw(self.image, self.x, self.y)
      end
      return self
  end
  
  ExplorerWindow = {}
  function ExplorerWindow:new(x, y, image)
      local self = Sprite:new(x, y, image)
  
      function self:draw()
          -- Here I want to call draw in Sprite
      end
      return self
  end
  
  function love.load()
      explorerWindow = ExplorerWindow:new(200, 200, love.graphics.newImage("res/window.png"))
  end
  
  function love.draw()
      explorerWindow:draw()
  end
