You can help when no one else can. You can secure their confidence when others fail.

Practical experience shows that nothing will so much insure immunity from drinking (using, acting out in a compulsive-obsessive behaviour) as intensive work with other alcoholics (addicts).

You can secure their confidence when others fail. Remember they are very ill. (p. 89, A.A. 4th Edition)
