If we really want to love we must learn how to forgive.

O teach me how I should forget to think (1.1.224)

We forgot how to know when we learned how to please.

And we forget because we must
And not because we will

Matthew Arnold, ‘Absence’ (1852)

And each day brings it's pretty dust,
Our soon-choked souls to fll
And we forget because we must,
And not because we will.

Ah! it is well we can forget,
Or who could linger on
Beneath a sky whose stars are set,
On earth whose flowers are gone?
For who could welcome loved ones near,
Thinking of those once far more dear,

Let us forget with generosity those who cannot love us

Experience has rude lessons, and we grow
Like what we have been taught too late to know,
And yet we hate ourselves for being so.
