Good point [Self-referential humor wink]. But on the other hand, someone once complemented my manner at work (a very rare thing, and I think it was honest), for being respectful of other people's views using such techniques. And I assure you that after saying these politenesses, I go ahead to politely but assertively, even aggressively contradict people whenever I need to. [Douglas Hofstadter would be proud, self-referential wink #2.]
