WHEN George Orwell noted that writers are fundamentally 'lazy' he did not have either columnists or me in mind, although I cheerfully admit to being infected with the disease. Except for a brief spell during unemployment when I undertook a weekly column for Sunday, I have never presumed to instruct the nation on a daily or weekly or fortnightly basis. Thus, in the conventional sense I am not a column writer although from time to time I make forays into the territory.
