Someone new to love while I'm without you

VI

Kick up the fire, and let the flames break loose
To drive the shadows back;
Prolong the talk on this or that excuse,
Till the night comes to rest
While some high bell is beating two o’clock.
Yet when the guest
Has stepped in to the windy street, and gone,
Who can confront
The instantaneous grief of being alone?
Or watch the sad increase
Across the mind of this prolific plant,
Dumb idleness.

Philip Larkin
