it grows unknown— in some dreadful instants

A faithful "I am sorry" 

will sometimes save the Heart—

when every other Savior fails—

I want to take hold of your Hand

and tell you that Love lasts—

though it grows unknown—

in some dreadful instants—

We are eternal—dear,

which seems so worthless, now—

but will be by and by,

all we can remember—

because it owns our own

and must give them back—

[Emily Dickinson {1830-1886} 'A faithful "I am sorry"', from New Poems of Emily Dickinson]
