I haven't the foggiest idea really. I'm fairly certain he doesn't lie to me because he isn't hesitant to tell it like it is. I don't know why he would ever start lying to me; we don't mince words with each other and don't *****-foot around the truth. So, would I be able to tell? Maybe? Because we've always been so straight with each other, I suspect I would probably get a feel for a lack of authenticity in what he was saying; I think he would probably behave in a way that would set off my radar in some way because it would just be different. But that's my best guess.
