Happy World Smile Day, everyone! Today is a great day to encourage the acts of kindness we can do to put smiles on each other's faces. 

The story of World Smile Day begins with the inventor of the smiley face, Harvey Ball, who created the iconic image in 1963. After its creation he thought the meaning of the symbol, good will and cheer, had become lost as a result of its overuse across the globe.

To combat this, he proposed that people should devote one day a year to smiles and the true meaning of the smiley symbol, which is doing good and performing acts of kindness. That is when he declared that the first Friday in October should be World Smile Day. This idea grew over time and is now a trend that exists worldwide!

To celebrate World Smile Day, we want to stay true to Harvey Ball’s belief in helping people smile by performing acts of kindness. When we are kind and supportive of one another, making each other smile becomes easy.
