Many, in fact, too many, persons deliberately dodge questions. They listen and understand them, but then try to sidestep them.
And sometimes, they just challenge the inquiry:
“Did Blaine call you?”
“Why do you want to know?”
People try to duck questions, because, usually, they fear the potential consequences of the answers they would have to give. Children are particularly prone to do this to avoid accountability. And this argues that when adults dodge questions, they are being childish.
So you ask, what is the most common tactic used to fudge answers? Well, most culprits simply beg questions. That is, they give responses that really don’t answer the questions asked.
