Have started adding this disclaimer to my email messages
This email is an expression of the author’s views and author’s views only. No sir, computers and blackberrys don’t write.
Author’s views are generally in good humour and often in pun (rarely you might also come across a bout of humility), and are certainly not intended to be disrespectful or cause any kind of cataclysmic reactions. If they do however, then well, the author may chose to respond in kind, or even maintain a sinisterly silence which may then kindly be deemed as dignified.
