The way life is. Happiness and Sadness neither would exist without the other. without frowns we have no smiles. The upside down logo was designed by Hope 4 The Hopelessness. A way to say “I am fine but really I am not!”
Example: The upside down of things is you pissed me off but I can’t spread my unhappiness to the world so I smile instead of giving you the pleasure of seeing my frown.
