The Effect of a Smile

The other day I was thinking about how much all the small stuff affects us and our surroundings. Just a small act like a smile can open up new people and connections.
The other day I had such a nice short but powerful moment just because I shared a smile with a stranger. There was a band playing jazz on the street. Most people were randomly passing by without showing they cared or even notice the band, but an older man around 70 years old stood beside them and danced slowly with a wide smile from ear to ear.
 We get eye contact and shared a smile for at least for 2 seconds. It felt like we shared a special moment of happiness because we both were enjoying the music. Suddenly this old man runs towards me just to be able to tell me about the song. Apparently he used to dance to it with his wife, he even showed me where they met for the first time. To see the old man sharing his happiness was very nice and enjoyable.
Happiness can spread if you share a smile:)
