The smile that you forgot

You smiled for a second
At a friend you barely knew
You hardly remembered them,
it was the least that you could do

But that friend you barely knew
Needed a smile that day
You may not have stopped to talk,
But you helped them on their way

So much so, that smile you gave
They passed it on again
To another who was in need
Of some cheering from a friend

This sharing of the smile
It travelled very far
And eventually it did die out
With a trail like a star

But with each set of lips
Whose straight line became curvy
Some cheer was felt inside
And helped others feel more worthy

We don't chose which of our actions
Spark a change and which do not
Just don't give up - remember what you can manage
With the smile that you forgot
