LOL, I am really good at this Christian sermon thing. I am a raised Christian, what can I say? ;-)

but some or most people always want to claim that skill of perfection and that isn't right at all.

Now that you know that, you don't have to be like most people, do you? By not showing yourself to them as their own reflection, they can relax and just be who they want to be for a change and not think they have to be. Of course, this only works if you don't worry about what others think of you (while you still can care about what you think of them).
