We
cannot put a noose around another man's neck without first hanging ourselves.
Henry David Thoreau
Love
reckons hours for months, and days for years; and every little absence is an
age.
John Dryden
There
are no rules to friendship. It must be left to itself. We cannot force it any
more than love.
William Hazlitt
Sometimes,
when one person is missing, the whole world seems depopulated.
Lamartine
