For tears must flow to wash away

A thought that shows so stern as this:

Forgive, if somewhile I forget,

In woe to come, the present bliss;

As frighted Proserpine let fall

Her flowers at the sight of Dis,

Ev'n so the dark and bright will kiss.

The sunniest things throw sternest shade,

And there is ev'n a happiness

That makes the heart afraid!
