How is friendship born?

"How is friendship born?" Jean-Marc asks Chantal
"Certainly as an alliance against adversity," he continues, but maybe there's no longer a vital need for such an alliance."
"There will always be enemies," rejoins Chantal.
"Yes, but they're invisible and anonymous. Bureaucracies, laws," responds Jean-Marc. "Friendship can no longer be proved by some exploit."
"We go through our lives without great perils, but also without friendship."
