Pubdate: Thu, 05 Mar 1998 Date: 05/03/1998 Source: Calgary Sun (Canada) Author: Craig Schroer I READ the letters to the editor sections of many newspapers and have noted the Sun is unusual in its habit of attaching parenthetical comments to its readers' letters. Your editorial board has the luxury of opining on a daily basis and should therefore refrain from attaching one-liners to other people's letters. An insistence on getting in the last word is juvenile and reflects poorly on your editorial judgment and on your newspaper. Craig Schroer (Many of our readers love our comments.)
