a poem by William Blake

There is a smile of Love
And there is a smile of Deceit
And there is a smile of smiles
In which these two smiles meet

And there is a frown of hate,
And there is a frown of disdain,
And there is a frown of frowns
Which you strive to forget in vain,

For it sticks in the heart's deep core
And it sticks in the deep backbone--
And no smile that ever was smil'd,
But only one smile alone,

That betwixt the cradle and grave
It only once smil'd can be;
And, when it once is smil'd,
There's an end to all misery.
