A smile is such a simple thing
And yet, in its own way, it adds a touch of tenderness to any day
A smile can take the darkest cloud, and turn it inside out
For a smile is the beginning of what love is all about.
A smile can be the little seed that starts a friendship growing, with its warm, straight forward message
“You’re someone well worth knowing”
Heaven and earth seems closer
For at least a little while, when people draw together
In exchanging ‘just a smile’.
