I agree with you, Jason. I am not berating those that you would call quiet or reserved. I myself am a quiet and reserved person that prefers to remain unnoticed unless it benefits all for me to engage.
What I am speaking to is an internal battle that each of us plays out. I am not speaking to you in reference to those you see in your life (whether loud or quiet) I am speaking to you. Period. Not anyone else!
I would never berate. I would admonish even to the point of discomfort (if not even especially to a point of discomfort) for the sake of those that will listen and take a step forward as a consequence of hearing something no one else will tell them for fear of hurting their feelings.
