A friend is one who walks in when others walk out.

The Night is Darkening Around Me
by Emily Bronte

The night is darkening round me,
The wild winds coldly blow ;
But a tyrant spell has bound me,
And I cannot, cannot go.

The giant trees are bending
Their bare boughs weighed with snow ;
The storm is fast descending,
And yet I cannot go.

Clouds beyond clouds above me,
Wastes beyond wastes below ;
But nothing drear can move me :
I will not, cannot go.
