Yzma:  All right, I’ve had enough of this. Tell us where the talking lhama is and we’ll burn your house to the ground.
Kronk:  Er, don’t you mean or?
Yzma:  [even more angrily]  Err, tell us where the talking lhama is *or* we’ll burn your house to the ground.
Chaca: Well, which is it? That sounds like a pretty crucial conjunction.

Ever notice how quickly people can slip in a small detail that makes all the difference?  It can be anything from the quickly spoken disclaimer at the end of a commercial for a pharmaceutical to “We have to pass it so we can know what’s in it”.  You have to pay attention to just about everything that is said and done in order to know the true motivations and goals of others.  It’s rare in my life that someone I didn’t know very well doesn’t, at one time or another, try to sneak something into our dealings.  Heck, it’s not uncommon that I’ll work with someone for years, with no issues, and then one day they try to tweak our relationship in some small way that hurts me.  Whether it’s a politician, a lawyer, a salesman, or even friends and family, always know not only what they said, but also what they mean.
