BQ:  I bet we've all experienced it. You wonder if a person is the best thing ever, or vicious and crazy. One moment they're the kindest ever, and then they cuss you out, screaming, out of the blue. Within a couple of hours it's like it never happened. 

So what's the truth—are they totally loving or absolutely hateful? What's the baseline? Luke 6:45 says, "the evil person out of his evil treasure produces evil, for out of the abundance of the heart his mouth speaks." 

Don't discount hurtful words; they can be a look at the very heart of a person.
