The issue is one of integrity. It's been said, "You either have it or you don't." Now the truth is none of us are perfect. We wouldn't need Jesus if we were. But if you don't make good decisions outside of the classroom, if you haven't refined your value system, that will bleed into the classroom. In what way I can't predict, but it will happen. Maybe in the form of bad advice or whatever.
Let me give you an example. I hired a bunch of nurses. During orientation, I was discussing that we only had software licenses for a few of the computers in the office and they would have to take turns entering patient data on the ones that did. One nurse spoke up and said, "Can't you just copy the software."
I responded respectfully that "Yes I could, but technically that would be considered theft, it's also called software piracy". Is wasn't a month or two, until we noticed this nurse was turning in excessive overtime dispite the fact that she had a very very light patient load. And she wouldn't come into the office and help even when she didn't have patients, yet we were paying her a full-time salary. We tried to address it, but she didn't respond and we fired her. We learned later that she was working for another firm at the same time she was drawing a full-time salary from us. Which explains why she rarely came into the office after she saw her patients.
The point is that the same character flaw, the same lack of integrity that allowed this nurse to suggest we steal the software, allowed this nurse to steal from us.
If you don't have good values, it's going to show up in other ways.
If you want to be a really great teacher, spend some time examining your character and make it as Christlike as you can. You will have more positive influence on your kids than you will ever know in this lifetime.
I can agree that people who steal are likely to steal from anyone, if they think they can get away with it. Now, please tell me what people who go to Chippendales might do. Are you afraid they will interact sexually with students? Discuss sex in the classroom?
Please remember that there is a LOT that goes on with a person that you may not know. Is it MORAL to assume that I am depraved because I have been to a Chippendales show and fire me, while the teacher next door is carrying on an affair that you don't know about?
