Hans Bølling created The Optimist and the Pessimist, and they create a stability much needed in the every-day life.What is more, both characters can express much more than positivity or negativity. The Pessimist features droopy eyes, while the Optimist has a big smile on his face and both feature bendable arms that can exclaim in joy or lower in frown.
Whether you are one or the other, the Optimist and the Pessimist express the possibility of change of your perception, depending on your current state of mind.
