Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
Friendship is one of life's treasures, in which a stranger suddenly becomes a confidant and ally in life's travails. Like two musical notes or two colors that enhance each other, friends bring out the best in each other. How can we promote friendship? We must search for it and recognize it, but also test it and nurture it. Ultimately, our lives will depend on the loyalty and love of our friends.
