My gut feeling. Hasn't lied before. :>
We really want to be careful when it comes to our judging others. We get sound council from the bible which states: "Stop judging, that you may not be judged. For with the judgement that you are judging, you will be judged. And with the measure that you are measuring out, they will measure you." (Matthews 7:1,2)
If they are respectful and have manners. Basic manners says a lot to me about someone.
