For instance, I tell my students not to sit on top of the desks in my classroom... but I do it all of the time. I also tell people to be on time, when I am sometimes late. Oh, and my critique of my husband's driving is laughable when you look at my DMV printout.
I think we're all hypocrites and if I were to tell you to stop being hypocritical, then that would be hypocritical. See the messy Catch 22?
I can't talk about this without being guilty of what I'm talking about.
But putting that aside (because otherwise this would be a REALLY short and repetitive post), I have to say that I haven't dealt with a disproportionate number of two-faced Mormons versus two-faced Gentiles.
Most people have seen and interacted with people who know and espouse methods by which you should do things or live you life, but fail to operate by those methods themselves.
When people do this, I usually don't call them out on it--I really don't enjoy confrontation--but just take what they say with a grain of salt. As Carrie Ann said, it really is about integrity.
