Hoppie and I were discussing verbal tics yesterday. Hoppie has a coworker who will preface the response to any question he knows the answer to with "so." If he's not sure of the answer, he prefaces his response with "Um." Wouldn't it be awesome if everyone did something like that? You would know immediately, before the answer even began whether it was knowledge or speculation. No more would we be in the situation where someone presents speculation as fact, it would immediately be obvious that you couldn't rely on the answer with certainty. This delights me. I wonder if I could cultivate a tic like this. It's practical and useful.
