Does a single tear make a difference?

Does a single tear
make a difference?

I know it does -
when it is straight from the heart
pure and salty...

I shall cry an ocean...

does a single smile
make a difference?

I know it does -
when it is straight from the heart
pure and sweet....

I shall laugh
straight into the sun...

does this wanderer
make any difference at all?

I know I do
when in silence I sit

and nothing is done
...yet nothing undone...
