Samaritans is an organization that supports and helps people in distress. Its members are volunteers. To alert the general public to suicide, the organization installed a screen next to a phone booth in the subway. When the phone rang, you could see who was calling and why. If somebody answered the phone, he or she had the chance to become a volunteer. If unfortunately nobody picked up the phone, the person on the screen committed an irredeemable act and the following message appeared on the screen: Let us not miss a single call.
