Picking up the telephone, Alan Stern knows he'll hear just about anything from heartbreak to loneliness to not getting to go to the school dance.

The people who call Stern at the Teen Talk "warm line" are average teenagers who feel the need to, well, talk….

Organizers call it a "warm line" instead of a hot line because it's a place where teens call long before it's a life-or-death situation.

Notes
Dean Whitehead, editor of the LA County Department of Mental Health e-Newsletter sent me the following update concerning this term:
"Warm line" is a generic term for a non-emergency, non-crisis support and referral telephone response service. They offer immediate access to live help and are a cost-effective alternative to crisis lines. Warm lines are often staffed by consumer peers, medical or other professionals, consumer advocates and/or volunteers, and may offer assistance in more than one language. The term has been used since 1978, and possibly earlier, following publication of the article, The WARM LINE: A Primary Prevention Service, by Patricia G. Adkins and Trisha D. Ainsa in Research Communications in Psychology, Psychiatry & Behavior.
