I just don’t get that phrase. Yet, I hear it or read it, frequently. What, the speaker’s been lying all the time til now? And I should trust what he says?? That phrase just puts my hackles up. I think I understand why they say it – they want to emphasize what follows and make sure the reader or listener notes the truth of the statement, but I contend it shouldn’t be necessary in the first place. For the life of me, though, I can’t come up with a replacement phrase. Thoughts?
