to be happy, interact more with each other,
there are smiles and smiles
some show love and complicity, others sympaty or joy, and so on,
I put together some smiling faces, most of them did smile towards me, warming me, for a life, for day or for a minute
Some tell you "I understand you" others smile to the photographe, taking them or as answer to what I told them, but a smile is always welcome
look at some, until "enough"!
