A Mural of Positivity

A mural can change everything.
The drab walls of the regional rail train station
Turned into fun flowers filled with love.
I contrast this with the graffiti that follows me everywhere.
Painted on bridges, tree trunks, 
Innocent walls just minding their own business.
And I ask myself,
Am I contributing to beauty and joy?
Or am I adding to anger and destruction?
