Many people write to newspapers and magazines to express their opinions. Letters to the editor must carry the writer's full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.

"People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship," said social worker Ken Yip, "and this is what is causing a lot of family problems." When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer's signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
