Moreover, when looking at this unlikely duo, I arrived at an idea that happiness and sadness are a pair of polar opposite emotions that you can’t turn your back on. They are contagious and overwhelming. Indeed, how in the world is it possible to say ‘no’ to these two love bugs? Just look at them. They touch your soul with their eyes – the one with his constantly worried look and the one with her perpetually smiling face! What a duo!
