Yes, but I think that when we make mistakes there is also an opportunity to deal with them in a correct and tolerant way. Thus, despite sometimes making mistakes, we can serve both as an example of how to deal with mistakes, and how to turn errors (which are fundamentally undesirable) into something positive. We can exemplify how mistakes are not the end of the world and how we can pick ourselves up after falling.
I think that many times examples like this can be very valuable.
The very act of letting a younger one see that the role model is open for being corrected, is to me as valuable as to see the role model in being the corrector.
I agree with this.
